Simple, straightforward, nothing extraneous -- exactly what I look for in such an addon. Thanks Benji for sharing your tab counter with us!

If all you want is a tab count and nothing else, it'll work as long as you don't have a dark theme.. For me, it had black text w transparent bg on dark theme.... had to pull up a magnifier app to read it.

This has no Preferences section so you won't be able to customize the bg/fg colors either. If this is something you need, you may want to check out: 'Tab Count Icon by lllusion3418', 'Tab Counter (Tilwa fork) by tqdv', or 'Tab Counter (fork) by vhfmag'


FF v89.0.2 on Fedora 33 Cinnamon

Black on dark blue is difficult to read in default & dark themes. It's fine in light theme, but I think light theme is ugly.

Working for me (FF 63.0.1 32bits). Simple, no options. Sits in the tab bar. Discretion ok.

Does not work. Firefox version: 60.0.1

Needs update to support new Firefox black tab bar
