Firefox 41 arrives with Hello instant messaging, Account profile photos, and multiple search engines on Android

Mozilla today launched Firefox 41 for Windows, Mac, Linux, and Android. Notable additions to the browser include instant messaging via Firefox Hello, profile photos in Firefox accounts, and different search providers in the search panel on Android.

Firefox 41 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 target — even in a world increasingly dominated by mobile apps.

Desktop

The most important addition to Firefox 41, from Mozilla’s point of view anyway, is support for instant messaging. This addition is being made as part of Firefox Hello, which Mozilla calls “the first global communications system built directly into a browser.” When you’re on a Hello video call, you can now send and receive instant messages as well in Firefox for Windows, Mac, and Linux.

Next up, Firefox Accounts, an account system that provides access to Mozilla services, is getting slightly more personal. You can now add a profile photo in Firefox for Windows, Mac, Linux, and Android.

Last but definitely not least, Mozilla is moving towards requiring that all Firefox add-ons are certified and digitally signed through addons.mozilla.org, regardless of where they are hosted. In Firefox 40, the browser started warning users about unsigned add-ons.

Firefox 41 was supposed to automatically disable extensions that haven’t been certified. That has now been delayed until Firefox 43, though the browser will still offer a preference that allows signature enforcement to be toggled (you can turn off xpinstall.signatures.required in about:config).

In Firefox 44, both the beta and release versions of Firefox will not allow unsigned extensions to be installed, and there will be no way to override this.
