@oldrawgabbit Just disable system WebView and be done with it 😁
No, just kidding — don't do that, it might be a good idea if you use it like a normal phone, rely only on a few basic apps and use Firefox Mobile as your browser, but a lot of other apps rely on it and will just stop working — like for real, not just stop receiving notification as with Play services, they will just crash.
Unfortunatelly, even pricacy-centic apps like ProtonMail rely on it.
