Off topic, but has anyone noticed Firefox on iOS has gotten quite slow? It happens when I switch from another app to Firefox, and then tap the URL bar to highlight the text in preparation to type either a URL or a search query, the whole app will stop responding for anywhere from 1-5 seconds. This happens even on a fresh restart of the phone or after killing the app.
I'm using an iPhone 12 Mini on the latest iOS but I've noticed it for a few months now. It might sound minor but when everything else on the phone (including Safari) is so snappy, it's very noticeable.
