GrapheneOS OK, now I have another question... How about TOR? The browser, not the network. Does it have site isolation?
I ask because it split from Firefox long ago, and it has some flags on that I usually run Firefox with as well, but are not and have never been default. Things like privacy.firstparty.isolate
Which isolates all forms of site data from the first and third party websites to that exact website. Tor has this on by default, Firefox does not...
If that is not "site isolation" especially after also having isolated processes, then what is left after all processes and all site data being isolated?
For Firefox Android, I saw the bugzilla report on isolation not being complete. For desktop they claim it is complete, but they could be referring to the isolated processes through Fission...
Their "network partitioning" they claim is complete. Stronger on the Nightly builds, which is why I use them. Its not just cookies despite the name "Total Cookie Protection"
