Add a option to clear private data on exit automatically just like your pc version. Also your browser leaks ur ip via webrtc so i would like to see a way to disable it. Your adblock (this includes pc version as well) isnt that good, it misses common ads such as google ads, and duckduckgo ads. Finally, i want a option to disable webgl for security reasons, and i would like i way to add custom adblock lists for android to make it more efficient
WebRTC fingerprint block will be available. You can track the issue here
We are going to work on clear data on exit as well very soon https://github.com/brave/browser-android-tabs/issues/93.
