There was a discussion here about removing Gecko mobile browsers from ‘Recommendations’ because at the time they did not provide per-site process isolation. I presume that has not changed, but I am left wondering, because Gecko-based browsers did feature, are mobile browsers such as Firefox Focus as good or a better option than Cromite (Chromium-based) for use as an ephemeral mobile browser, where the user is only using it for web searches and logging into alias accounts?
Ironfox would certainly do better than Firefox Focus anyway, since Mull had great hardening but Ironfox dev has added a lot like just recently disabling HLTS but did many subtle changes to reduce the threat surface
I highly doubt that’s the case as it integrate strong privacy protections, and maintaing a different browser program wouldn’t make sense. Firefox Focus is just a epehemeral Firefox that is slightly hardened and with a reduced feature set.
I don’t know why so many people in this forum reduce FF’s security shortcomings to site isolation. Read what I wrote in the thread you linked and you will see that it’s by far not the only problem.
