Is there a way to transfer my browser profile on Android between Fennec and Firefox?

Telegram is the best social network. Not so much a private messenger.

As for risks… http://kremlingram.org/ has the Russian ties well-documented, even if theystretch the evidence at times, the latest border cross leaks are proofs enough

https://privacypass.github.io/ has helped somewhat

There are apps that block opening apps longer than some amount of time.

Can you recommend one for Android?
