Known bugs:

Changing the browser font size requires either the current page to be reloaded and the app restarted once, or the app to be fully restarted twice
If you restart the app while private mode tabs are open, they close, but the browser stays in private mode (you can switch back by pressing the tabs icon in the tab drawer)
Sometimes tab drawer normal/private mode tab switcher becomes out-of-sync with browser mode
Add-on list A-Z sorting doesn't work correctly when the device language is set to something other than English

Unsure which file to download? If your device is recent or has more than 4GB of RAM, get the arm64 variant, or otherwise get the armeabi-v7a variant.
