Useless. Doesn't appear anywhere Noté 1 sur 5 étoiles

Shows up nowhere.

But where? Noté 2 sur 5 étoiles

Potentially very useful tool, although I can't seem to find the crucial information.

Good, but not that good Noté 3 sur 5 étoiles

No need of "Tabs: " those who install it should know what the number means this just take more addonbar space.
At last make a option to deactivate this.

It takes up a lot of space, otherwise nice Noté 3 sur 5 étoiles

Still works when others don't Noté 3 sur 5 étoiles

The latest firefox release removed the addon bar and so the popular "tab-counter" ( and "TabCounter" ( addons aren't working yet. This one still does. :-)

Note: It shows the *total* number of tabs you have open, not per-window.

@developer: Any way to remove that annoying right-side margin? It would be a perfect lightweight addon otherwise.

Very poor Noté 1 sur 5 étoiles

Bad overly bloated display. Takes a lot of space for no reason
Only shows global count and not per-window
Has no configuration
