You are on iOS. There is only safari. Any other "web browser" is just a skin over safari

Yes I know everything is wrapped around safari. But I like having Firefox syncing across devices.

Edit: ah forgot my vpn was off, usually clears all that up for me. Much better now

Just a note: If you have a Windows computer, Apple has a plug in for Firefox and Chrome that syncs bookmarks to iCloud and Safari.

Linux machine but maybe it works anyway?
