A corrective release of Firefox 147.0.1 is now available, featuring three fixes:
- The 'Compression Dictionary Transport' mechanism added in release 147 has been temporarily disabled due to compatibility issues with some websites using this technology. For example, there is a failure to work with the ChatGPT website. To restore support for content compression via passed dictionaries, you can use the setting 'network.http.dictionaries.enable' on the about:config page. proxy server An error in the implementation of the Freedesktop.org XDG Base Directory specification has been fixed. Due to this error, despite the relocation of profiles, add-ons, settings, and internal databases to the directory '~/.config/mozilla', the browser continued to create an empty directory '~/.mozilla/extensions'.
- A problem with determining the time format in the Intl.DateTimeFormat method has been resolved, which led to incorrect time display on some websites (for instance, instead of '12 GMT-06:00', it showed '12h GMT-06:00').
- Additionally, it has been reported that support for the old sidebar will be discontinued this year. In Firefox 136, a new implementation of the sidebar was added, which can be displayed in a collapsed view showing only the buttons for available operations (in the old panel, modes were changed via a dropdown menu, while in the new one, changes are made through side buttons). In nightly builds of Firefox 148, the new panel is enabled by default. In the second quarter of 2026, all users of the old panel will be automatically transitioned to the new panel, though an option to revert to the old panel will be available. In the third quarter, the code for the old panel and the option to revert will be removed from Firefox.
