I use Opera Mobile on my phone because it's literally the only mobile browser which UX isn't completely botched.

In Firefox you cannot choose the folder to save files to, which is something I absolutely need because I mostly download porn but once in a while I have non-porn and these two must be in different folders.

Chrome doesn't support text reflow on zoom. I don't even have a comment because this makes it literally impossible to use desktop view which usually provides better experience.

I'm not even a power user. These features are IMO extremely basic things. Opera's built-in VPN is nice for browsing Twitter but that's an extra I could live without.

First world problems.
