As I said somewhere else, to get more compact tabs you can go to about:config and search for a setting called browser.tabs.tabMinWidth, I usually change the number to 20 (the default minimum width is like 70) and tabs are allowed to become roughly as narrow as in chrome. And if by “more compact tab bar” you meant how tall tabs are, there’s the browser.compactmode.show setting, put it to “true” and then in the Firefox menu under More Tools → Customize Toolbars you can select “compact mode” in the “Density” menu on the bottom, which makes the tab bar and toolbars shorter
No I meant vertical hight. The horizontal width is way better than in Chromium, same with the “scroll tab feature” which works well better.
That second setting is beta is no longer supported so its not shown
Beta? It isn’t experimental, it was an official feature that is no longer supported (even if it still works perfectly).
