This may be a controversial position but I actually enjoy using Firefox. Vertical tabs, better profile management, etc. have all been welcome things I had in other browsers (cough Arc cough) that have made it bearable enough to use Firefox as my daily driver. They may not be as privacy-focused as some of the other derivatives of Firefox but they’re sure not Chromium.

Vertical tabs are still broken. Fullscreen mode (F11) hides all the chrome except for the vertical tabs. Who wants this?

They seem to be actively working on vertical tabs for Chromium right now: https://chromium-review.googlesource.com/q/message:+vertical...
