Mozilla has officially released Firefox 146, the latest version of its popular open-source browser. This release brings significant, long-awaited improvements that improve the viewing experience, especially for Linux users. The most notable change on the Linux side is that full fractional scaling support is now available by default under Wayland. The goal is to provide a much clearer viewing experience without requiring users to fiddle with complex settings files or experimental features.

According to Mozilla, this change makes the browser’s rendering much more efficient. This means that text, icons, menus, and cursors on web pages are clearly displayed on the screen at the correct location and size, rather than appearing blurry. Because Firefox can now properly read GNOME and GTK screen measurements, most of the issues previously encountered with integer scaling, which caused elements to be resized incorrectly, have been resolved. However, it’s noted that minor glitches may still occur in rare cases.
The update isn’t just focused on Linux; It also includes practical improvements for Windows and macOS users. According to the release notes, Windows 10 users can now automatically back up their passwords, bookmarks, and other data. These daily background backups are stored locally, and users can encrypt them with a password if they wish. Mozilla announces that this local backup feature will soon be available on other operating systems.
On the macOS side, a significant architectural change has been made to improve system stability. Firefox now uses a dedicated GPU process on macOS. This feature prevents the browser from completely crashing when a problem occurs with graphics code like WebGPU or WebGL. In the event of an error, instead of closing the browser, the GPU process is simply restarted, ensuring an uninterrupted user experience.
Other user experience improvements include more direct answers to queries like flight status in the search bar and an Accuweather-powered weather widget on the “New Tab” page for users in EU countries. Furthermore, along with security improvements, the browser’s infrastructure has been strengthened with new patches. While Ubuntu users will receive the update automatically in the background, Linux Mint users will be able to access the new version through the update tool starting December 9, 2025.
So, what are your thoughts on these display improvements and backup features offered by Firefox? Have you updated your browser?
