Hey, I switched to Firefox because I liked its UI better (after Quantum though)

Yes. Because the UI and UX of a tool that you use everyday matters. The average user will hold ease of use over privacy 9 times out of 10. In my case though I wasn’t able to use FF for a while due to the lack of debugger support for a project I was working on. Now it comes down to me having to work on multiple projects at once so tab groups and organization are key. Now don’t get me wrong, once Chrome totally kills adblockers I’ll drop Chromium browsers like a bad habit, but the point still stands though, FF could use some UI improvements.

Or Mr. Incredible being sued for saving a guy commuting suicide..

Well, super bad breath is not your ordinary bad breath. It would possibly melt your lungs faster than the fire. Bacteria that can thrive in superman's body is not to be messed with.

I literally swore off Firefox for half a decade because they removed and broke Panorama with their engine rewrite, so yes.

Yeah I thought it had that feature already but I wasn’t seeing it. I’ll have to look again.

Which ones? Besides sending a tab from mobile to desktop it doesn’t have tab groups or vertical tabs. Those features rely on extensions and/or custom css.

I use FF. But I also use Chromium based browsers out of necessity. I understand where you’re coming from but what’s also going to screw us is Mozilla not keeping up with the latest features which is something they’ve struggled with. At the end of the day they have to give people a reason to switch and use FF as their main browser. Simply saying “better privacy features” isn’t enough for the average user.

IMO there are none. They are all janky. Your best bet, (and what I may start doing), is to make separate folders in your bookmarks bar and add any tabs you want in there as a group. Not ideal but it works.
