Thank you all! So, the two browset concept still exsists. :)
I am a big fan of fennec/mull, especially with uBlock, but long time I did not knew that per site isolation does not work on firefox for android. But to be honest, I am not really sure how big that problem really is. Is it right, that in the end, fennec/mull is not sandboxed at all on android? Even not via the standard app-sandbox?
Then I switched to Vanadium with Bromite as my login-browser. But updates on Bromite are unfortunately really late sometimes.
So I do not know what is better in terms of privacy and security - using only Vanadium or also a second browser wirh shortcomings for logins.
Brave is not FOSS, right?
Thank you all and best regars
