Firefox Quantum gets even faster in its latest update

With the recent launch of Firefox Quantum, the team at Mozilla overhauled the browser with a new look and a significant speed boost. Now, Mozilla is following that up with the release of Firefox 58, which adds further enhancements that should speed things up and smooth browsing out even more.

Firefox 58, Mozilla explains in a blog post, takes advantage of improvements in its engine that allow it to paint your screen using a dedicated CPU thread. The goal? To make things less janky when you're initially loading text and images on a page. According to Mozilla, the move to offloading screen painting to a dedicated CPU thread has resulted in a noticeable boost in performance, showing framerate improvements of 30 percent in its tests (from 31 fps to 40 fps).

Aside from a speedier Firefox, Mozilla has added a few other, smaller goodies in version 58. According to the release notes, Firefox now supports autofill for credit card details, copy and paste for screenshots, and screenshots now work in Private Browsing mode. Firefox has also changed how it caches and retrieves JavaScript, further speeding up page loads.

If you already use Firefox, you can get the latest update now. New users can download Firefox Quantum directly from Mozilla.

  • Unfortunately, it's been crashing a lot for me lately (even before v58). Usually just a tab, but occasionally the entire browser. I'm wondering if it might be an extension update, though the new extension format should be more robust and isolated.
  • I like Quantum update very much and use it most of time. It lacks with few bugs as compare to Chrome. - Do you know that Firefox Quantum acquire less cpu usage than Edge( & Chrome also).
    Don't believe me, test it on your system by opening blank page. And see the difference in 'Task manager'. ☺ In coming days, chrome will have an ultimate competitors.
  • A blank page is not exactly telling the whole story.
  • Chrome also lacks some FF stuff.
  • Forget CPU usage, Chrome just loves my RAM, and NEVER lets it go.
  • quantum, easy on RAM
  • I just wish ff would support touch screens better.
  • Go into the menu and go to customise and then click on density and there is a touch option, it's not great but it is usable with a stylus.
  • Yes. Touch screen stopped working right away.
  • I just wish LastPass would get their extension to work properly on Android. I have been an LP user for years and am on the verge of switching over this.
  • I use LastPass. I'm on Windows Phone, not Android, but I assume LastPass is no better on Windows 10 Mobile than on Android. Maybe this would approach could also work for you: On Windows 10 Mobile, LastPass is not integrated in the browser; it's a separate app. I open it whenever I need to lookup a password. If it's a site I use a lot and am OK trusting the browser with it, I'll let Edge store the password for the next time. At least for me, while not perfect or as good as a built-in extension like on the desktop (where LastPass is installed in my Edge, Firefox, and Opera browsers), this at least ensures I can get into any site on mobile within about 30-40 seconds.
  • Not sure what this has to do with Firefox, but okay.
