"We've completed our annual ESR transition audit, where we review Firefox's changelog for issues that may negatively affect the privacy and security of Tor Browser users and disable any problematic patches where necessary. Our final reports from this audit are now available in the tor-browser-spec repository on our Gitlab instance."
"Tor 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."
"If you find a bug or have a suggestion for how we could improve this release, please let us know."
Refreshed application icons. "Earlier this year we spent some time artworking the Mullvad Browser logo into the various assets needed to support its release – including application, installer and document icons that conform to each platform's conventions" and "and started working on new icons for Tor Browser in parallel."
New homepage. "Tor Browser 13.0's homepage now features the new application icons, a simplified design, and the ability to "onionize" your DuckDuckGo searches by switching to the DuckDuckGo onion site."
Bigger new windows. "We've bumped up the max size of new windows up to 1400 x 900 pixels and amended the letterboxing steps to match. "
Technical notes. "We're pleased to report that we've made the naming scheme for all our build outputs mutually consistent."
