Firefox shipped sandboxing on Android years ago (before chrome) and then removed it. I’m not sure you gain much from it on Android. It eats up ram making performance crap on cheap phones and apps already run in their own app user context to isolate what they can access.
Definitely no shady VPNs run by white westerners though. Theyve all got impeccable morals through ans through. Glad you cleared that up.
