I don't mean to disagree with you, but isn't IronFox pretty slow? I was using it for like one to two weeks after I got an Android, but I switched to Bromite because of the horrible performance.
Maybe it's because of my devuce though (I'm running an 2018 second-hand Pixel 3a with EvoX)
I don't feel it is particularly slow, but I have a Pixel 7. It may be slow on 7 years old HW unfortunately :( Chromium is probably better optimized.
I got used to bottom bar on Firefox and since then, I am unable to use Chromium based browsers on mobile. It is just so bad to have the bar at the top. So Bromite is not an option for me.
