I tried Orion after reading this, but other than uBlock Origin I haven't had much luck with getting extensions to work. I guess the extensions I use don't really overlap with the 70% they do support. If they've been working hard on this for years, I have to wonder what will happen first, actual mobile extension support on iOS through Kagi or a Firefox release for iOS.

The entire Orion browser feels like a beta product to me. But at least I've got uBlock on my work phone now, so that's cool I guess.
