Tor Browser 9.0a4 is now available from the Tor Browser Alpha download page and also from our distribution directory.

Note: this is an alpha release, an experimental version for users who want to help us test new features. For everyone else, we recommend downloading the latest stable release instead.

This release features important security updates to Firefox.

Tor Browser 9.0a4 contains updates to a number of bundle parts, most importantly Firefox (60.8.0esr) and Tor (0.4.1.3-alpha).

In our ongoing efforts to reach more users with Tor Browser, we include native Macedonian bundles for the first time and ship Tor Browser for the aarch64 architecture on mobile (note: the aarch64 build is not currently available on Google Play. You can however download it from our distribution directory, along with its signature). Additionally, we have implemented fixes for accessibility support on Windows systems (big thanks to Richard Pospesel for the hard work here), which now deserve a wider testing. Finally, letterboxing is now being enabled by default. Please give it a try if you can, so we can iron out bugs before we ship it to all users starting with Tor Browser 9.

Similarly to the stable series we include a fundraising banner to help us getting more donations. Please donate if you can!
