My setup on GrapheneOS with all the exploit protections on except some off for apps with compatibility issues. Thoughts?

Firefox is not secure on mobile, Vanadium is a great browser made by the GrapheneOS devs
Can you elaborate?
I'm on the go right now. This is a quote for an old privacy guides snapshot, but when I was looking for it, I saw some articles from April saying that this was no longer true, so further searching needed when I get home
People in the comments already have "Avoid Gecko-based browsers like Firefox as they’re currently much more vulnerable to exploitation and inherently add a huge amount of attack surface. Gecko doesn’t have a WebView implementation (GeckoView is not a WebView implementation), so it has to be used alongside the Chromium-based WebView rather than instead of Chromium, which means having the remote attack surface of two separate browser engines instead of only one. Firefox / Gecko also bypass or cripple a fair bit of the upstream and GrapheneOS hardening work for apps. Worst of all, Firefox does not have internal sandboxing on Android."
Oh, i didn't know it was a fork. I'd take adblock over it though, just for the fact it blocks rogue malicious javascript along with ads.
I generally recommend Firefox for people that don't use it, but there are more secure forks too if that's your jam.
I mean Gecko based browsers are actively recommended against on mobile. Chromium based browsers are recommended. Also I use mullvadVPN DNS based ad blocking, and I also have Brave that has built in ad blocking. Do yourself a favor and ditch adblock in favor of Ublock origin
never heard of it. by whom? for what reason?
I haven't really dived into this but I'm pretty sure GOS dev are one of the groups to recommend against it
