Privacy Browser 3.10.1 has been released. It fixes a bug that caused the Import/Export activity to crash on start because it was looking for a TextView that no longer existed which explained encryption limitations on Android KitKat.
Another bug was fixed that prevented custom user agents from working correctly because the number of user agents had changed with the removal of Internet Explorer. While testing this fix, I also discovered a long-time bug that caused Domain Settings to crash if the custom user agent was set to the text
Custom user agent. This was enough of a corner case that it probably was never encountered in the real world, but it is fixed now.
