Firefox still doesn’t have a native vertical tab bar.
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.

At least the extension APIs are powerful enough to have an extension that does a decent job (or even a great job, in the case of extensions like Sidebery), plus there’s a way to hide the regular top tabs. That’s not the case with Chrome.
