Firefox for Windows 10 is coming 'soon' but details remain scarce

Mozilla quietly revealed its plans to bring its Firefox web browser to Microsoft's Windows 10 operating system last week. However, that's pretty much all we know at this stage, other than Mozilla says it will be released "soon".

Mozilla started developing a version of Firefox that would have worked with Windows 8 and its "Modern" touchscreen user interface in 2013, but after a number of early releases and delays, Mozilla abruptly ended development of the Windows 8 version in 2014, claiming that only a few people were actively testing the browser.

Mozilla has not indicated any word on what the Windows 10 version of Firefox will be like, saying only that it plans to "provide an independent and high-performing alternative to the stock browser."

  • As in bring it as a universal app? I'm sure a lot of people will be happy about that.
  • I would be happy))
  • This makes me wonder. WIll EVERY app created specifically for Windows 10 really work across ALL devices?
  • It will if it is built as a Universal App. That is the whole point.
  • If it's a Universal Windows Platform app then it will run on all Windows 10 devices.  Microsoft's new Edge web browser is a UWP app that runs on all Win10 devices so far.
  • Im hoping to that it was UNIVERSAL. Phone and PC...
  • Me too...
  • Ur right.
  • I guess everyone using a windows service will love to have universal app for everything..
  • Not necessarily. Apps are designed to only have a subset of features specific to mobile devices. Power users will want to have the "full"/desktop version.
  • Not necessarily on your not necessarily. Apps don't HAVE to be just a subset of features specific to mobile devices, that has just been the trend because in the past apps have only been on mobile devices with the exception of Windows 8/8.1 which never really took off. On Windows 10, the push is on for full functionality of apps as universal apps, like Office, etc. They CAN be more, if the develpers will just get it right.
  • I'm happy I thought they just were done after scrapping the old one
  • It'll be a failure of it's not universal. So get it right Mozilla. And it this gets to be universal.... Maybe then Google will feel the urge to release a mobile app on Windows phone(universal chrome browser)
  • Please...we don't want the shit laggy chrome browser.. It will ruin the fluidity of the Windows OS. Microsoft Edge and Firefox will be more than enough
  • Some of us use Chrome for very specific reasons. I'd be pretty happy if Chrome came to Windows phone. I mean I'm an adult, and if I have to wait a couple extra seconds for a page to load I can deal with that.
  • Very specific reasons... Like actually wanting Google to get the most out of their privacy violating data collection? (no other browser gives them as much telemetry as Chrome)
  • Actually I use it because of extensions that my company wrote so I can do my job easier. Seeing as none of my personal data gets input, I really couldn't care less what Google gets.
  • Extensions are key here... hopefully they figure out firefox and chrome extension support soon Posted via the Windows Central App for Android
  • This type of attitude still makes no sense to me. You can say it sucks, but millions of people use Chrome and it has absolutely outperformed IE in JS performance for years. Edge may be better, but that doesn't suddenly make Chrome suck. Having a competitive browser scene is only a good thing. It drives Microsoft to be more innovative. Edge would NOT be as good as it is without Chrome. Why people don't want to see competition due to blind fanboy stuff when that competition drives their favorite company to do more is beyond me. Posted via the Windows Central App for Android
  • But still Internet Explorer holds a greater market share, so that means whatever million rely on Chrome, much more than that rely on IE.. Amd I seriously hate chrome's frequent crashing capabilities, like, oh, shockwave flash has crashed (they still mention ot as shockwave), and chrome has crashed and etc..
  • I would bet money this will just be an updated x86 version.
  • More like an updated Android version.  Which isn't a bad thing at all.  FF is great on Android.
  • Big Windows can't run Android apps though
  • No, but they can use the new app porting tools to port the Android version to a Win10 Universal App.
  • Only Windows 10 Mobile has the Android subsystem. Big Windows cant run the recompiled Android apps. http://arstechnica.com/information-technology/2015/04/microsoft-brings-a...
  • You have used it? It sucks... It really does and that's why I used chrome on android Firefox sometimes didn't even work so I really don't know how someone can say "its good" and I had two different android phones and it wad bad on both.
    So I hope they make a better work than what they do on Android. Because Firefox on Android sucks and I am not alone on that.
  • Was atrix one of them?
  • I am not aware of any sites that FF on Android doesn't render correctly.  But it may just be that it works well on the sites I use. Out of curiosity, on what Web sites does FF fail for you?  I think it works great and it certainly is much lighter than its main competition, Chrome (which is a bloated, battery sucking mess). No matter what, I think we can agree that it is streets ahead of both IE and the current version of Edge.  It'll be great to have some serious competition in Windows 10 browsers.
  • I don't see the point. They already have a working browser on the desktop, so why not adapt its UI for touch?
  • If they make it universal, it means that ARM tablets and phones could also run the same browser. (Firefox for windows phone)
  • Only difference is it'll be using edge's engine on ARM. Cause I doubt the situation has changed since they 1st approached ms about special sdk access
  • Based on the context of the article "for iOS and Windows 10", they presumably mean they're bring it to phones too.
  • Can't wait to see the flood of universal apps coming at us in the next few months!
  • That's may be .exe baby... Don't excite... I'm sure Mozilla is not going to bring a window phone version. I asked them about a browser for windows phone a year back. They replied saying that not going to release any app for widows phone in near future. And they said currently very busy with android...
  • That's because the Windows 8 version of Firefox could not run on Windows Mobile, and today Mozilla does not have enough resources to make a dedicated .NET application for their browser. But thanks to Visual Studio 2015 and compiler tools, Mozilla can use the same Android build and compile it on Windows Mobile. This sounds like science fiction, but its a huge change for the platform. King's Candy crush runs in Windows Phone today thanks to this technology, it uses the same iOS version.
  • The landscape was completely different a year ago. I asked Candy Crush a year ago if it would ever come to Windows Phone and they said they have no plans, then shortly after they appear. There's no evidence that this will be an .exe except a hunch of yours based on outdated information.
  • unless Microsoft changes its policy on 3rd party browsers on WIndows Phone, I doubt this will be a universal app
  • Microsoft already supports Android apps, so even Chrome could run on Windows Mobile, but I doubt Google will make their browser available to Windows mobile due to the poor market share. But wait until Samsung or LG release a flagship phone in 2016 with Windows and Google will start to worry about Chrome on Windows mobile.
  • Exactly what I was thinking
  • I rather think this is the Android version of Firefox (same git build) but it uses Visual Studio 2015 tools to run Android code on Windows mobile and Windows 10.
  • And that would be just fine with me.  FF on Android is excellent.
  • And it also gets updated very frequently, since Firefox Android team already has a lot of experts in this field, so I think having Microsoft the possibility to run Android apps on mobile is a huge achievement that will help OEMs and carriers to start caring again about launching products with Windows instead of Android.
  • Big Windows can't run Android apps, only Windows 10 Mobile can do it.
  • Not true, once it is brought in to visual studio 2015 it can be made into a universal app with simple code changes. Now it will work on all windows 10 devices. Anything that can access the windows store.
  • No, only Windows 10 mobile has the Android subsystem to run Android apps. http://arstechnica.com/information-technology/2015/04/microsoft-brings-a...
  • once an app is compiled, it becomes native. so can run in any windows. the thing you refering is projectaa or something like that. you dont need that to run universal apps.
  • Again not true. Once it is in visual studio it no longer needs the android subsystem no matter what and is usable as a win app. You are getting this confused with something else.
  • No, there's only one way this works and it's through Project Astoria. If you read the linked article, it would explain that only Windows 10 Mobile can run the recompiled Android apps. The point of recompiling them is making them a Windows app. That recompiled app, however, needs the subsystem to work, and only mobile has that. I dont know where you got that there's two ways to port Android apps.
  • Nope, just like dipayanster pointed out. Once and app is compiled, it becomes native. My church app ported from android will be able to run on windows desktop as well as windows phone. Already confirmed with my developers who took extensive classes on it at Build this year. It's common knowledge which is why people keep telling you that you are wrong.
  • I don't know what your developers were smoking then. Project Astoria IS the way to recompile Android apps into Windows apps.
    https://dev.windows.com/en-US/uwp-bridges/project-astoria
    And, as I've said before, this is only on Windows 10 Mobile.
    So everyone (um... 2 people?) is wrong if they think that you can recompile Android apps for big Windows. You've provided no evidence to suggest what you're saying is true other than hearsay.
  • I dont need to provide evidence go look it up its true, your one link proves nothing. My developers and EVERY OTHER developer out there has said the same thing. You clearly don't know what your talking about. Candy Crush is a great example of this. IPhone and android app migration will work EXACTLY the same way, there is proof enough. Get off your high horse and stop responding.
  • I've listed two links: one that explains to your what Project Astoria actually is (and not whatever you think it is), and another from a trusted Windows reporter from a reliable website that explains that only Windows 10 Mobile can run recompiled Android apps. "Iphone and Android app migration will work EXACTLY the same way" This is fundamentally untrue and is proof that you're full of it. iOS and Android apps get ported in completely different ways. The link from ArsTechnica goes into detail about how each will be able to be ported to Windows, and they're certainly not going to be able to be ported the exact same way. Please do your research before so boldly declaring something.
  • Oh my gosh. It is pointless arguing with someone who has mo clue what he is talking about. Wish a mod would comment so atleast then you would stop your insolence.
  • Where can I download firefox for windows 10, I just get firefox-2015 latest update for linux, mac, windows 7/xp/vista/7 and android
  • I would be really happy for a Firefox universal app :) Firefox on my PC is my fallback browser if something doesn't work correctly on Edge.
  • Most Probably not. It'll be a program for w 10 desktop alone.
  • they chickened out during windows 8.1 ... why bother now ... we are getting better browser and chrome is already there 
  • Hopefully not another half-made browser that vanishes before anyone even knows it exists.
  • I had no idea they even made a modern app.
  • It didn't work very well, is why few people were interested in testing it while they worked on it
  • That's one sad looking fox.
  • LOL exactly. I didn't know about it until they shut it down.
    That's like keying someone's car because they wouldn't go on a date with you... except you forgot to ask them out!
  • Would be nice to see a universal one/ * speaking for phone version*
  • *XBOX ONE*
  • Yes yes.
  • Yes that would be awesome! I could finally have everything sync on my phone from my PC's browser! Edge looks good but I'm a Firefox guy.
  • Why? Just because Firefox worked so well so far, when something new comes that is better or atleast equally as good AND integrated I to the OS making ot better id rather go with that. Just throwing it out there. Nothing wrong with trying new things and giving up the old :).
  • I love and respect Firefox, but I am quite happy with Edge for now :D
  • As long as Microsoft keeps updating Edge, then Edge it will be. Edge has been great as of last few updates.
  • I totally agree!! I have been really liking Edge. Super fast page load times, and smooth performance. If Microsoft keeps up with it (and I have a feeling they will) it will be a formidable browser.
  • Does Edge have (or will have) the ability to sync favorites and saved passwords across devices?
  • Across all windows devices yes, I dont know of any plans for them to release it on any other devices.
  • Also need for phones....
  • Dnt need it now :/
  • ^This
    Now we have Edge, we don't need it :P
  • We need as many options as possible.
  • Edge is very good, but you can't manage Favorites very well. They also need to sense if non-touch and tighten up the spacing between favorites. I'd like Firefox everywhere, including my phone.
  • #theapparecoming
  • Should be on WP...
  • Bring it to mobile too please :D
  • Stop me, oh ho ho stop me, Stop me if you think that you've heard this one before...  
  • Edge all the way. #beingEdgy
  • Yeah, I'm in love with Edge, but lacks the addon ability of Firefox.
  • Lacks it, for now.
  • Still edge lacks alot on phones ......
  • It's still in development. I'm sure it will get much more awesome in the coming builds.
  • If this is universal and makes it to mobile and maybe even Xbox One I would be ecstatic!
  • You wouldn't be the only one.
  • Edge but Firefox, that would make me happy
  • A proof of app gap going to vanished & banished,windows 10 going to exceed the bar of awesome to dominating Os
  • Still man, this isn't what people want in the OS , there are alot of games and apps needed , and social apps all need to be overhauled
    For me I'm optimistic about windows 10 and universal apps and my next phone is "cityman" (940xl) but it hasn't yet happened , windows 10 has to shock us more !
  • One day, dude. One day.
  • It would be great if it was released for phones too
  • Coming "Soon" ... You Keep Using That Word, I Do Not Think It Means What You Think It Means ~
  • I think it's near 29/7....
  • FTW!
  • Exisiting Firefox works well on Windows 10 TP.  My favorite extensions work.  Flash plug in occassionally crashes but hard to tell if that is a Firefox or Adobe compatibility issue.
  • They should have written it like that.... "free yourself FROM Firefox" how funny it sounds if one changes just one word.
  • Soon = 29/7 or near that.....
  • Well...........
    For sake of custom-skins/themes, i'll use firefox.
    Anyway Edge is overall winner.
    Agree?
  • Hands down.
  • For phones plz!
  • Hopefully as a universal browser
  • Windows Phone needs Firefox (and other alternative browsers). IE11 mobile is painful to use. Posted via the Windows Central App for Android
  • That's what the new Edge browser is for, and it will replace IE for mobile completely.
  • Edge doesn't help if one needs a browser that also syncs with Android and Linux devices. Not everyone uses Windows devices only. Posted via the Windows Central App for Android
  • Edge for W10M is faaar faaar better than IE.. But not even close to UcWeb ( in terms of more features ) .. May be Edge will evolve and outperform UC in near future :)
  • Let us hope so! But already looking great, I can do things in Edge for W10M that were impossible in IE mobile. I believe MS will continue to develop Edge.
  • Off topic..what about Live Lock Screen Beta..has MS abandoned it..I really liked the lock screen patterns in that..
  • W10M is still evolving man.. Give it some time... I'm pretty sure they won't leave our lockscreens as simple as wp8.1..
  • I'm surprised they took interest again after cancelling the windows 8 version. Probably pressure from imminent public release of Edge. I've also noticed they recently added a reading view button to Firefox. I can only imagine this is to compete directly with Edge. Competition is good :)
  • Good to see apps coming to W10... But in the case of browsers.. EDGE ... Not a fan of Chrome.. But will keep Firefox as a back-up if Edge fails to load any particular website
  • Mobile too. Then Edge and Firefox and fun.
  • I've never been a big fan of FireFox. But the more the marrier. Hopefully they actually release a final product this time, instead of deciding to cancel it like with the metro version.
  • Good bye third party browsers. Hello Edge
  • Unless they're also bringing it to Xbox and Mobile too I really don't see a point.
  • Ha ha,too late, it's time for edge
  • I've noticed Firefox has gone downhill lately, for me it has anyway! Never liked chrome but I've found that to be more functional and smoother to run.
  • Firefox actually uses less memory than Chrome at the moment. So that's why I'm using FF. Chrome devs are probably aware and working on it.
  • Yes it does uses less memory and battery than chrome. Chrome is good on PCs Firefox and ie11 for laptops.
  • For some reason it takes ages to load pages and my java script stops working quite a lot. So I switched to chrome and I've not experienced any problems. Hopefully one day I will use Firefox again, I preferred the layout!
  • Well let's see if Developers gets attention onto this!
  • If it's universal I might consider staying with WP.
     
  • I will be using edge. Its so advanced and handy.When we needed apps, they didn't make. Now we don't need them.
  • So does the current version of Firefox not work with Windows 10 at all? Or does it require a re-written version? I guess I assumed most Windows 8 programs would have been compatible still.
  • It's working fine. They meant the store version AKA ' metro app'.
  • The desktop version works pretty well in W10, but I believe this refers to a universal app or a touch optimized one.
  • Heard this one before...
  • Will love it if it's a universal app that works across every windows device.
  • Firefox universal app is needed across both phone ,PC and tablet , while keeping support for the desktop Firefox browser application
  • People still use this? It always looks like some independent high school project.
  • Would be very exciting if it came to Windows phones too. However, after the Windows 8/Firefox debacle, I'm worried they may just use Project whatever to bring the Win32 version over.
  • hmm good point, completely forgot about the 4 'bridges' Microsoft is working on. I think the web app one is already working and theres a couple submitted to the store. wonder how well the x86 bridge will work, if it can simply sandbox the desktop program and still allow for the feature set of win32 programs that would be crazy o_O
  • IE works fine for me, especially with multi touch trackpad of my laptop. Multi touch feature doesn't work properly on Chrome or Mozilla.
  • Windows phone is growing......growing fast. Happyyy!!!
  • This is probably Firefox for Android but compiled with Visual Studio tools of 2015 so it can run on Windows Mobile (smartphone, small tablet) or Windows 10 (desktop). I knew Mozilla would jump to Windows development now that they don't have to hire specialized WP developers for this app since they can use the same code base which is running on Android.
  • That would only work if they only plan to support phones. Big Windows can't run recompiled Android apps. Plus, Project Astoria isn't even available yet.
  • Good point, I didn't knew Android apps compiled on Visual Studio 2015 will only work on Windows 10 Mobile. Thanks for clarification.
  • It's over for Firefox. I'm switching to edge.
  • I wish I could roll with Edge but its too broken to use.
  • People use this terrible browser I always use IE
  • And then they'll cancel it about a month or two after they start testing.
  • Free yourself? More like free your available memory for Firefox.
  • Wimps.  They backed out of building for Metro/ModernUI and now that the WinX train is about to take off, its "have I got an app for you!"
  • And an alternative it shall remain.
  • Unfortunately, I'm probably going to wind up using this. Or Chrome. Edge is simply terrible. I've really tried to like it, but its only redeeming quality is that it's included with Windows 10. I would say Edge, as a browser, is maybe 20% complete right now. I realize it is still in beta, but I hope Microsoft works overtime to make it into something usable. It was supposed to be fast, but it simply is not. It takes a second just to view your favorites, and pages often crash in the background or fail to load. When they do work, it is no quicker than any other browser I have used, and the program is a memory-hog, with only 5 tabs easily managing to eat 6 GB (about 50%) of RAM. Add to that, the lack of options, tools, plug-ins, right-click menus, clunky favorites, and a generally dumbed-down interface, and I see nothing there to like. I'll keep using  IE 11 for a while while it is supported, but already the heavy legacy coding really bogs it down, and Microsoft has recently stripped out the ability to set search providers or accelerators (right-click to look up a word, search an address, ect.). When that runs out, it's, "Hello Firefox or Chrome."
  • You can set the search provider in the settings
  • If you go to: http://www.iegallery.com/en-us/addons?callback=true&featuretype=1 You will see that the once extensive list of Accelerators and search options has been reduced to a list of only 20 (2 of which are default MS search options, and 3 others aren't even searches: AdBlock+, Flash, and Silverlight). At least the Google search option is back, as it was missing a week or two ago. One of my old selections, look up with Dictionary.com, is no longer present. Much like with the slow disappearing act performed by the apps in the old Gadgets store, I fully expect this selection to be retired soon.
  • The Windows 8 version of Firefox was so horribly slow. It was totally unacceptable. Scrolling websites was totally laggy and jumpy. Unusable on a low power tablet device. That was the reason why no one used it, and that was also the reason why the project was dumped. I love Firefox for the plugins, and on most of my devices it performs good enough. But the rendering engine is really poor, compared to other major browsers. If they want to make a successful browser for Windows 10, and want it to run on slower devices and WP as well, then they have to put lots of work into a new rendering engine. People expect a browser that scrolls butter smooth, even on a phone. If they cannot provide that, then it won't be successful...
  • This is just another attempt to test the waters. A wize man said "Do or do not, there is no try" so fuck Mozilla.
  • I prefere IE, ffox crash a lot
  • Now? Lol! No I don't need Firefox now, I'm OK with Internet explorer. Stay on Android
  • Yes. Let's not have no alternatives or options.
    With that mentality who cares if no app comes to Windows land anymore. Glad that the os is dying Posted via the Windows Central App on my Lumia 640 XL
  • Yes, bring FireFox to Windows 10 & Windows Phone 10.
  • Why waste the effort?  And why say something unlikely to happen? We were supposed to get a Windows 8 Firefox but that took ages to get nowhere. Run the Android APK on the phone and existing desktop version on the Desktop.  Job done.
  • Edge all the way, but options aren't a bad thing. I'll install it as my backup browser, same as it is now.
  • Only if its universal.
  • I currently use Firefox developer edition daily, currently not seeing any major changes. Maybe later updates.
  • I use Firefox Nightly on my Windows PCs, my Linux PCs, and my Android devices. Posted via the Windows Central App for Android
  • Great news! My favorite desktop browser coming to Windows 10.
  • I like Firefox, but so far, Edge has proven to be a high performance browser that has nothing to envy to Firefox and Chrome... Except for extensions, but we all know that's coming in the future as well, so I'm positive it will be even better.
  • Wait and see vivaldi browser.
  • I would be happy if it was universal
  • firefox should also release browsers for windows phones
  • I'm using Android's. So I won't use Edge till it becomes available there too!
  • Firefox was great on Win 8. Why is it crashing on Win 10?
