Mozilla has released version 139.0.4 of the Firefox web browser. The new update provides solutions to the freezing and stuttering problems that users have been experiencing recently, while also closing critical security vulnerabilities. This version, which increases the stability of the browser and increases its security level, positively affects both the daily user experience and system security.
Mozilla has solved the problem in Firefox
In Firefox 139.0.4, freezing problems that occurred when switching between applications or entering certain panels of the browser have been eliminated. The problem of difficult selection of drop-down menus in the in-page search feature, which users frequently use, has been fixed.

In addition, various selection problems that occurred when triple-clicking on text have been resolved with this version. A significant bug for Windows users, the issue of incorrect use of the file name when an image is set as the desktop background, has also been fixed. These improvements provide increased performance, especially during heavy use.
In terms of security, the closure of two critical vulnerabilities has allowed Firefox to better protect its users against cyberattacks. Mozilla continues to improve the browser experience with security patches and performance updates.
Users can download the Firefox 139.0.4 update from the browser menu via the “Help” and “About Firefox” tabs. Alternatively, the update is available via Mozilla’s official website or the Microsoft Store for Windows 10 and 11 users.
This allows Firefox users to quickly switch to a more stable and secure browser experience. What do you think about this development? You can share your views with us in the comments section below.
