A visual candy - always know the number of opened tabs.
This extension does not have whistles nor bells, but it does add a tiny visual indicator to your browser – the number of opened tabs.
What is it good for?
If you like to be in control (OCD maybe?) x or if you just need an eye candy addition to the boring toolbar, or if you have plenty of tabs opened and you simply wonder how many of them exists - this marks your tabs.
