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 use Firefox on Android exclusively. Having ublock for youtube on my phone is great... But since updating to Android 13 watching full-screen video in FF has been an issue. Usually it requires that I restart the app to work.
