Privacy Browser Android 3.13.3 was released on 13 March 2023. It contains a fix for the current tab not always being the active tab after restart. When Privacy Browser is stopped in the background because the OS needs the RAM, it stores the current state of each WebView in an app bundle called the SavedInstanceState. When it is restarted it restores the state of each WebView. All of this happens asynchronously, meaning that each tab is reloaded simultaneously. Sometimes this would cause the logic that restores the active tab to fail, with one tab being displayed to the user but a different tab being set as the current tab. Hopefully this fix handles all the corner cases.
