create workspace

[Foni86]

I may simply be an idiot, but in your screenshots I see that you have work spaces like those in opera, "tableros" in Spanish. But I don't see how the hell to activate or use them

hi,
Firefox don't have workspaces, one of the icons in my ScreenShots is of Simple Tab Groups extension and the other is just the bookmarks menu icon.
