Mozilla today released Firefox 80.0.1, an out of band update designed to fix crashes caused by GPU resets and issues affecting downloads triggered by browser extensions.
Firefox 80.0.1 also fixes rendering issues on some websites that are using WebGL to render content, a bug that leads to broken text being rendered on Linux systems (with Xorg and NVIDIA graphics) and on Windows 10 devices (with Direct3D 11).
This version also addresses “a performance regression when encountering new intermediate CA certificates” and the “zoom-in keyboard shortcut on the Japanese language builds.”
The download issues are caused by missing third-party cookies in the download requests which could result in incorrect downloads.
Mozilla fixed this issue by adding relevant cookies to all extension-initiated download requests, as well as to all browser-triggered ‘Save as’ downloads.
This happens “even when tracking protection is configured to be very strict (e.g. blocking all third-party cookies),” according to Mozilla Browser Engineer Rob Wu.
Firefox 80.0.1 also fixes crashes when surface creation fails, potentially related to GPU resets or OOM events.
Mozilla patched this issue by adding a null pointer check, designed to avoid the crash.
“The resulting rendering might not be completely correct, since the mask surface (inferred from crash report stack traces) is not available, but this should be preferable and recoverable as opposed to crash,” Mozilla Senior Software Engineer Miko Mynttinen explained.

Firefox 80 was released week ago with a new and faster extensions blocklist that enhances the web browser’s performance and scalability.
If you have automatic updates enabled in Firefox’s options, you only have to restart the browser to have Firefox 88.0.1 installed automatically.
If you want to install it manually, you can download Firefox 88.0.1 from the following links:
If the above links haven’t yet been updated for Firefox 80.0.1, you can also manually download it from Mozilla’s FTP release directory.
