This release is updating Firefox to 60.9.0esr, Tor to 0.4.1.5 [4], and NoScript to 11.0.3. This release also includes various bug fixes. On the Windows side, we should now have support for accessibility tools [5]. On the Android side, we added support for arm64-v8a devices [6].

This is expected to be the last release in the 8.5 series: on October 22 we will switch to the 9.0 series, based on Firefox 68ESR.

Note 1: Due to some issue with Google Play's new requirement for 64bit versions [7], we have not yet been able to publish the Android x86 and x86_64 versions on Google Play. We hope to be able to fix this in the next days. In the meantime the x86 version can be downloaded from our website [8].

Note 2: There is an issue with the aarch64 version on Android 9 [9] causing a crash on every launch. We are working on a fix for this issue.
