Mullvad Browser 13.0 released with multilingual support
Since we released Mullvad Browser in April in collaboration with the Tor Project, it has been well received and its use has been steadily increasing.
Mullvad Browser 13.0 is our first stable release based on Firefox ESR 115, incorporating a year's worth of changes shipped upstream. As part of this process we've also completed our annual ESR transition audit, where we review Firefox's changelog for issues that may negatively affect the privacy and security of Mullvad Browser users and disable any problematic patches where necessary. The final reports from this audit are now available in tor-browser-spec repository on Tor project Gitlab repository.
Particularly notable are the accessibility improvements we've gained as a result of the transition to Firefox ESR 115. Mullvad Browser 13.0 is our first release to inherit the redesigned accessibility engine introduced by Mozilla in Firefox 113. This change promises to improve performance significantly for people who use screen readers and other assistive technology.
Finally, we're happy to see "DNS over HTTPS" settings revamped (under "Settings" > "Privacy & Security" ). Using this interface, it is now possible to correctly set a DoH server without fallback or leaks, by selecting "Max Protection".

Bigger new windows
On browser start, the new windows should be bigger by default and present themselves in a more useful landscape aspect-ratio for the majority of desktop users in Mullvad Browser 13.0.
The rationale behind the new window size and its impact on letterboxing can be found in Tor Browser 13.0 release blog post.
Updated search engine selection
For convenience, we added multiple search engines by default:
- Mullvad Leta (requires a paid Mullvad account)
- Brave Search
- DuckduckGo HTML
To change your default search engine, go to "Settings" > "Search" > "Default Search Engine" and use the dropdown to select another one.
Other notable changes
- Enable cross-tab identity leak protection in "quiet" mode
- Enable built-in URL anti-tracking query parameters stripping
- Change devicePixelRatio spoof to 2
- Lock RFP in stable builds
The full changelog is available in our releases notes.
Going forward the names of all our build artifacts should follow the format
For example, the Linux package for 13.0 is named
If you are a downstream packager or download Mullvad Browser artifacts using scripts or automation, you might have to update your scripts.
Our focus has now turned on making Mullvad Browser as usable as possible, without compromising on privacy. Our goal is to make it easy for everyone to use Mullvad Browser as their default browser.
