Firefox on iOS is a horrible experience. My desktop I have switched to Vivaldi so I can easily sync tabs between desktop and phone. I don’t love Vivaldi but the overall experience is superior to Firefox on both.
Would prefer safari on my Linux desktop and use it on my phone
And I hope Apple doesn't manipulate the "power usage" data that always claims Safari is the lowest-power best-battery-saver browser on their platform.
I run Safari on MacOS for only that reason, that it allegedly gives me an extra hour or so out of my laptop vs. Chrome or Firefox. Of course, I should actually benchmark myself and find out.
I switched to Safari on iPhone because I was always logged out of stuff on first load, super annoying. I miss the syncing, but not that much.

Chrome and Firefox are already on iOS – if they're allowed to swap out their rendering engine, is this something customers will actually care about?
