New Release: Tor Browser 10.0a8 (Android Only)

by sysrqb | October 8, 2020

Android Tor Browser 10.0a8 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.

We are happy to announce the first alpha for Android users based on Fenix 81. The Desktop version was released at the end of September.

Over the last four months we adjusted our toolchains, finished our proxy audit, re-implemented the user interfaces, and fixed a lot of issues that came down on us due to the switch from Firefox 68esr to Fenix.

Tor Browser 10.0a8 ships with Fenix 81.1.2 (see Mozilla's blog post for more information about this new browser). As this is the first alpha version based on Fenix we expect more bugs than usual. Please report them (with steps to reproduce), either here or on Gitlab, or essentially with any other means that would reach us. We are in particular interested in potential proxy bypasses which our proxy audit missed.

Note: We are aware of two reproducibility issues in this version. The first issue is coming from the ordering of symbols. The second issue is due to the order in which supported locales are added.

When will the Android version of the tor 10 browser be released?is android version 10 based fenix?

10.0a8 is based on Fenix. We will release on more alpha version in the coming week (10.0a9), and if that version does not have any more significant problems, then we will release that as 10.0.3 in the coming week.

Heads-up: "intl.accept_languages" and "intl.locale.requested" are reset on every browser start and will just leak _current device locale_. So either modify them on each and every start or change *device* locale in Android Settings to English (US).
