Opened & Closed Tab Counter от Shajirr

If you open way too many tabs and don't close enough of them,
resulting in an ever-growing number of tabs left, this addon might help to track that and reduce their number.

It displays the delta between the number of tabs you opened and closed during the day, with green background for negative (closed more than opened), and red background for positive (opened more than closed)

Red background = you need to close more tabs,
maintaining green background = reducing the number of tabs.

If you hover a mouse over an addon's icon, it will display the current delta,
as well as separate numbers of opened and closed tabs.

Clicking an addon icon brings up a popup which displays the deltas for the last 7 days as well as their sum, so you can see more long-term stats there.

Addon icon needs to be pinned to toolbar first, since its needed for pretty much all of this addon's functionality.
