This is interesting because I’ve been thinking about switching from Debian to Arch. I’m already running Nix inside of my Debian installation to get more recent apps (I don’t like how snap interacts with the rest of the system, so I avoid it if I can).
Is there anything else on a more base OS level (like apt v pacman) that you’ve noticed is different, if you’re willing to share?
That is only mostly true now. There is an about:config setting you can turn on in FF 129 (released this week) which will let you have native vertical tabs. The implementation is only about half done, but it’s good enough for me to use alongside Sidebery Tabs.
You can track progress on vertical tabs in Bugzilla. They are also working on tab groups, but that work is at an earlier stage.
All in all, I think we’ll see vertical tabs in the next 6 months or so? As a devout Firefox user and resister of the Chromium monopoly, I am really excited.
