The Tor Browser 13.0 update brings a range of anticipated improvements. Notable enhancements include the introduction of a landscape aspect ratio, a resolution to the "red screen of death" issue, and various updates from Mozilla's Firefox ESR 115. Additionally, the update includes refreshed app icons and GUI elements while maintaining the familiar look and feel of Tor Browser.
The most significant change for many users in this release is the new landscape aspect ratio. Previously, Tor Browser's inner content window was limited to 1000 x 1000 pixels, which often resulted in compatibility issues with modern websites and triggered mobile versions of webpages. With the latest update, you can now adjust the size to 1400 x 900 pixels, providing a much more suitable browsing experience.
Tor Browser is still implementing its "buckets" system, which offers a limited selection of content window sizes. If the size of your container window exceeds that of your content window, Tor Browser will utilize letterboxing to fill in the gaps on the sides of webpages. This "buckets" system enhances the challenge for websites attempting to fingerprint Tor Browser users. The Tor Project anticipates that the most popular bucket will be 1400 x 900, which should ideally offer the highest level of anonymity.

The latest version of Tor Browser, version 13.0, has addressed the persistent issue of the "red screen of death" that has been bothering users since the release of Tor Browser 10.5. This problem has been resolved by introducing a new and visually appealing homepage called "about:tor" which removes the outdated Tor network connectivity check. Although this connectivity check may still be useful for non-default Tor Browser configurations, it is worth noting that none of the major Tor Browser variants utilize the "about:tor" homepage.
Furthermore, Tor Browser 13.0 is the first release based on Firefox ESR 115, offering various minor changes and improvements. Firefox ESR 115 introduces noteworthy enhancements for accessibility, including better support for screen readers, keyboard navigation enhancements for in-website calendars and date pickers, as well as optimized UI and content scaling for Windows users who have enabled the "Make text bigger" accessibility setting. Users with monitors featuring a refresh rate of 120Hz or higher will also benefit from improved performance, and Windows users can now utilize touchpad gesture navigation, specifically the two-finger forward and back gestures.
Most of the changes introduced in Tor Browser 13.0 are purely cosmetic. Your desktop will now display a more elegant app icon, and various elements of the browser's user interface have been enhanced. The "about:tor" homepage has also been redesigned with a more minimalist approach, including a convenient shortcut to the onionized version of DuckDuckGo. Tor Browser aims to improve user experience and make it more visually appealing. This revamp was inspired by Tor Project's work on the Mullvad Browser, which is a variant of Tor Browser that does not utilize the Tor network.
The Tor Browser 13.0 release can be obtained from the official download page and distribution directory. It is important to avoid installing Tor Browser from unofficial sources.
