gk7ncklxlts99w1 I see your point about Arkenfox, but that shouldn't prevent someone from making a Firefox fork that tweaks the source code to enable site isolation / IsolatedProcess. I'm not a developer, so I don't know the hurdles associated with such a change.
Yes, it shouldn't prevent someone from making it. You can't code, I can't either, so we just need to sit and wait for this feature to be available one day.
gk7ncklxlts99w1 Containers are considered dead, as this guy explains.
You don't use containers in Firefox for security, you use them for convenience, if you want to login to 2 different websites without having to opening and closing Firefox, you use containers. Its up to you to use them or not, they don't provide any extra security.
gk7ncklxlts99w1 Also, I want to mention that the GrapheneOS documentation explains that Tor has poor security, therefore has poor privacy. But as you mentioned, and as the guide that you linked mentions, Tor is the only browser that has the capacity to be truly anonymous. If Tor has poor privacy, then Vanadium must have even worse privacy. Something doesn't add up.
Again, privacy and security are two completely, completely different things.
Tor is private but not as secure, Vanadium is not private but more secure. Thats it.
gk7ncklxlts99w1 replying to https://discuss.grapheneos.org/d/2061-questions-about-grapheneos-and-related-topics/14. That sounds fair, but the phrase "Tor itself makes people into much more of a target" sounds very ominous and overly dramatic. I suppose it depends on the country you're in, if you live in a country that really doesn't like people using Tor, then ISP's might end up cancelling your internet. I don't see how it would end up in you being targeted by a state government or hackers (as the phrase might suggest, at least to me).
Its not dramatic, its a correct statement that warns people about possible side effects of using Tor. No one can guarantee your ISP won't make you a target if you use Tor, hence the precaution.
This is something you can again do some more research on the web .
