Firefox 152.0.2 is out with fixes for performance, translation, and cloud storage services

Mozilla is rolling out a new bug-fixing update for Firefox to address four bugs with translation, performance, and website compatibility.

A new bug-fixing update is now rolling out to Firefox users in the Release Channel. Less than a week ago, Mozilla fixed crashes on Intel Raptor Lake processors with version 152.0.1. Now, Mozilla has prepared yet another set of fixes that address problems with localization, playback issues of certain MP4 files, and performance issues on website that perform various encryption operations at once.

Here is the full changelog:

• Fixed some Settings section headings showing placeholder text instead of the translated name in certain languages.
• Fixed New Tab content not matching the browser's display language after it was changed.
• Fixed a regression that could break playback of some MP4 video files.
• Fixed a performance regression that could slow down sites performing many encryption and decryption operations at once, such as Proton Drive.

Firefox 152.0.2 is now available for download from Mozilla's FTP. Existing installations will get the update over the next several hours. The latest version will also be available soon on the official website, the Microsoft Store, and Neowin's Software page. You can find Firefox 152.0.2 release notes in the official documentation.

In case you missed it, Mozilla released Firefox 152 earlier this month. The latest feature update brought reworked settings with a more streamlined user interface, JPEG XL support, new features for Private mode, a new way to mute a tab (just type "mute" in the address bar), and many more. You can find the complete changelog here.

In other Firefox news, Mozilla recently published its roadmap, where the company detailed the upcoming Nova redesign and other features it plans to implement. Mozilla wants to make the new user interface easier to navigate and more modern, with a heavy focus on its privacy tools, such as its built-in VPN. If you are curious, you can already enable the new UI as described here.
