Mozilla plans to release a new point update for its open source Firefox web browser later today. Firefox 138.0.3 is a non-security update that fixes three issues in earlier versions of the web browser, including one crash issue.
If you use Firefox on the desktop only, you may ask yourself if you missed the Firefox 138.0.2 release. You may have, as this special version was only released for Firefox on Android.
Firefox 138.0.3: the fixed issues
Firefox 138.0.3 fixes a WebGL-related crash. Mozilla notes that Firefox could crash when websites that use WebGL were opened. WebGL, which stands for Web Graphics Library, is used to render 2D and 3D graphics using JavaScript.
Web games and other interactive or animated content may make use of WebGL. So, if you ran into crashes while running the recent version of Firefox, there is a good chance that this was caused by the WebGL bug.
The update fixes a second crash. This one occurred on websites where certain SVG effects were applied to very small areas.
Firefox 138.0.3 fixes two additional issues:
- Videos looked washed out on Linux under Wayland, if HDR was not supported on the system.
- The keyboard shortcut Alt-C did not work as expected in the sidebar search.
Mozilla has not published the official release notes at this time. The release notes will be published shortly after the Firefox 138.0.3. You can access them here afterwards to check them out.
The new update is only available for the desktop versions of the Firefox web browser. Furthermore, Firefox ESR are not updated, as they appear to be unaffected by the issues.
Mozilla plans to release the next major version of Firefox and Firefox ESR on May 29th, 2025. The following versions will be released on the day:
- Firefox 139
- Firefox 115.24 ESR
- Firefox 128.11 ESR
Now you: where you affected by one or several of the fixed bugs? How do you handle point updates usually? Do you install them right away, postpone their installation, or skip them? Feel free to leave a comment down below.
