Firefox 58 for the desktop is available for download now on Firefox.com, and all existing users should be able to upgrade to it automatically. As always, the Android version is trickling out slowly on Google Play.
Mozilla doesn’t break out the exact numbers for Firefox, though the company does say “half a billion people around the world” use the browser. In other words, it’s a major platform that web developers have to consider.
Performance aside, Mozilla also made functional and privacy improvements to Firefox Screenshots. You can now copy and paste screenshots directly to your clipboard, and Firefox Screenshots now works in Private Browsing mode.
As part of its plans to stop supporting WoSign and StartCom root certificates, Mozilla has removed six certificates from Firefox 58. Speaking of security, Firefox 58 also blocks top-level navigation to data URLs.
Mozilla today also highlighted Firefox’s Tracking Protection feature, but this is not new in Firefox 58. In fact, it was added to Firefox 42’s private browsing mode in November 2015. With the monster Firefox 57 release, Mozilla finally added an option to enable tracking protection outside of private browsing.
Tracking protection means Firefox blocks website elements (ads, analytics trackers, and social share buttons) that could track you while you’re surfing the web. It’s almost like a built-in ad blocker, though it’s really closer to browser add-ons like Ghostery and Privacy Badger because ads that don’t track you are allowed through. The feature’s blocking list, which is based on the tracking protection rules laid out by the anti-tracking startup Disconnect, is published under the General Public License and available on GitHub.
The feature got lost in all the other changes made with Firefox Quantum, so Mozilla wanted to point out that it’s great for not just privacy, but performance as well:
Separately, the same Tracking Protection technology will be added to Firefox for Fire TV this week — it will be turned on by default, but can be disabled for sites that don’t load properly. Mozilla is branding it Turbo Mode on that platform, however, “because it gives you a faster and less cluttered browsing experience” and because the company is apparently not interested in consistency.

When browsing with Firefox for Android, websites that function as PWAs will show a house-shaped button in your address bar. You can add that website as an app to your home screen by simply tapping the house-shaped button. Launching that new PWA will open it in full-screen, outside of the browser UI, and without an address bar.
Firefox for Android has also received improvements to its bookmarking feature. Instead of a dialog box, bookmarks are now shown in a full screen, where you can create and organize them in folders.
