The final push to start using Firefox over Chrome on Android might finally be thanks to the enormous selection of add-ons (Firefox’s version of extensions) coming out next month. Chrome doesn’t offer native support for extensions in its mobile app. Also, better security.
I would use Firefox on Android but I’m waiting until the security is on par with Chromium such as having internal sandboxing and site isolation.
Also since Firefox doesn’t have a WebView implementation, it has to be used with the Chromium based one so it doesn’t make sense for me to use two browser engines.
I made a similar comment on this article in [email protected] - for anyone who is blindly downvoting thinking this is some Google psyop, this is the explanation from GrapheneOS (who fortunately provide their own de-googled chromium-based browser Vanadium):
