It's working perfectly for me. I'm using Firefox 20 Beta 3. It's the best replacement for TabGroups Manager. The only thing it's missing that I would REALLY LOVE to have, is a toolbar button for switching tab groups. Another extension called TabGroup Switcher has that feature. It's really cool! I wish you could update your extension and add it. Any chance of that happening? Even updating it would be a miracle at this point!This user has other reviews of this add-on.
Isn't this extension already have that feature? It adds a drop down to the existing tabgroup button, and you can click on the group name to select the group.
