That's a severely outdated notion.
Not sure what you're trying to present here but we don't care about what Firefox on your smartphone is doing... Fenix isn't even the same thing anymore as fennec was, so you can't even compare. System services may also do strange things. Either way it's N/A because we don't even have smartphone support. So wtf are you doing pulling that kind of stuff in?
I asked about providing details on deliberate vulnerabilities that you say Basilisk has inherited from Firefox. You haven't, so far.
If you're talking about multiprocess firefox, then it's quite possible your OS had dropped the inactive process, too.
None of that is relevant here.
Please stick to topics that are relevant to this forum and this board and the original topic you started.
