Mozilla plans to release Firefox 84.0.2, a new version of the organization's stable version of the Firefox web browser, to the public on January 6, 2021.
Firefox 84.0.2 is the first stable release of the Firefox web browser in 2021; the next major stable release of Firefox is scheduled to be released on January 26, 2021.
The new Firefox release is not available at the time of writing. Mozilla is still preparing the release, but if there are not any last minute issues that would delay a release, Firefox 84.0.2 will become available in the coming hours.
Firefox users who have not turned off automatic updates will receive the update automatically. Those who don't want to wait for that to happen can select Menu > Help > About Firefox after the official release to initiate a manual update of the web browser.
The screen that opens displays the currently installed version of the web browser and runs a check for updates, provided that the functionality is enabled.
Again, this won't work at the time of publication of this article, but it will work later today provided that Mozilla will release the stable version today.
Update: The release notes are now available. Firefox 84.0.2 fixes a single security issue that is rated critical, the highest severity rating available. Mozilla notes:
A malicious peer could have modified a COOKIE-ECHO chunk in a SCTP packet in a way that potentially resulted in a use-after-free. We presume that with enough effort it could have been exploited to run arbitrary code.

You are probably wondering about the changes in Firefox 84.0.2. The preliminary release notes confirm that Firefox 84.0.2 will be a security update. No other release information is provided at the time, and the linked security page has not been published yet.
Mozilla won't publish security information before releases, but these will become available later today as well. The severity of the security issues fixed in the new version of Firefox is unknown because of that as well. In fact, it is unclear if one or multiple security issues have been addressed in the new Firefox version.
We will update the article once the information is published by Mozilla.Advertisement
