This is actually how people live now. It feels crazy to say this but I actually know people like this in real life who use their phone while “watching” a film. There has even been debate about whether production studios are dumbing down scripts to cater to people who are literally not paying attention. We live in insane times.
It depends how important the tab bar feature is to you. Firefox has pretty much every other feature you’ve listed there and would be my recommendation. Otherwise, Vivaldi has all of the functionality but isn’t FOSS and is potentially less private. It would still be a lot better than Samsung Internet in those areas, though.
