The official release data of Firefox 44 is January 26, 2016. This overview provides you with detailed information about the new release including new features and changes in the desktop version of Firefox and the Firefox version for Android.
Mozilla updates all channels of the browser that it makes available at the same time. This means that Beta, Developer Edition, Nightly and Firefox Extended Support Release channels will be updated as well.
This means the following version changes: Firefox Beta 45, Firefox Developer Edition 46, Firefox Nightly 47 and Firefox ESR 38.6.
Information below cover only Firefox Stable for the desktop and Android, and no other release channel of the browser.
Firefox 44 will be released on January 26 by Mozilla. Firefox is configured to download and install updates to the browser automatically, and if that is the case, users don't need to do anything to upgrade to the new version.
Since the update is not picked up in realtime, some users may want to run a manual check for updates in Firefox to download it as soon as it becomes available. This is done in the following way:
Firefox checks for updates manually then, and will prompt to download the update or download it automatically depending on its update preferences.
All versions of Firefox can also be downloaded directly from Mozilla. Please note that it may take a while before the new versions become available as downloads on Mozilla's website.
Firefox 44 is a rather uneventful update for the most part. It is the first version of the browser that will enforce add-on signing in the stable version of the browser.
As you may know, Firefox 43 offered a configuration switch to override the enforcement, and Firefox 44 will continue to offer the switch. In fact, Mozilla postponed the enforcement of add-on signatures in stable and beta builds to version 46 of the browser.
This means that you cannot load add-ons in Firefox Stable anymore that are not signed. Read our guide on running unsigned add-ons in Firefox if you want to continue running unsigned add-ons.
Video Support improvements
Information is scarce at this point, and Mozilla failed to link to a bug report that would shed some light on the changes.
The most like explanation is that Mozilla will set media.mediasource.webm.enabled in Firefox to true.
It means better support for HTML5 video in Firefox, especially on operating system versions that don't support Mp4/H.264 natively.
Improved warning pages for certificate errors and untrusted connections
Firefox's new warning page uses less text and a clear "go back" call to action. A click on advanced displays information about the issue (which the old warning page listed under technical details).
There you find an option to add an exception to access the site nevertheless (formerly under "I understand the risks").
Basically, less text on the page but all important information are still there. Plus, the message "your connection is not secure" is more direct than the old "this connection is untrusted".
Security updates are disclosed after the official release. We update the article as soon as they become available.
