Edit: Just realized you also can't have the same workspace open in multiple windows and have separate sets of tabs for each one. Or rather, you can only have a given workspace open in one tab at a time. That'd probably be a nightmare to code though, so I'm not gonna blame the dev for that.

I used this a while ago, and decided to come and check it out again. Still neat! But I wish I could put the icons directly on the toolbar so that they fit in with Firefox GX a lot better. It's literally the only thing I'm missing from having the GX experience that I want in Firefox.

Basically, the toolbar is moved from the top to the left when you install Firefox GX. There might also be an API for changing the icons through GX Mods, but I'm not certain about that. Might need to ask some people, I guess.

In any case, if an update happens that lets me add the workplace icons directly to the toolbar (and assuming I remember), I'm boosting my rating to five stars if it lets me. If we get even more stuff, well... I'll just wish I could give six.
