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.
Yes it does lag much more than chrome, even on S23U. Even with noscript enabled, actually. I am trying to get used to it for the last few weeks cause goddam noscript makes internet a better place.
