For the most part, all of the attention Firefox has received in recent months has been related to its speedy Quantum update, launched in late 2017. However, Mozilla announced today that it is cooking up a couple of small, but handy features that users can test right now as part of its Test Pilot program.
The first addition is the new Firefox Color extension, which is a simple tool focused entirely on theming. The extension allows you to customize portions of the browser, including background texture, text, icons, and more. Mozilla has included quite a bit of control here, so it should be simple to toy around with and find something you like. Just be careful not to burn your eyes out of their sockets.
The second new tool is Side View, which operates like Windows' Snap feature, but built into the browser. Side view lets you quickly open a second browser tab within the same browser space. Mozilla is positioning this as an easy way to compare shopping sites, news stories, and more. For Windows users who are already used to snapping websites next to one another, this may be a little redundant, but it's a neat addition nonetheless.
To check out the new tools, you can join the Firefox Test Pilot program, which is open to all Firefox users. Eventually, if they garner enough positive feedback, both features could be added to Firefox's default setup.
