Google Chrome Browser Extension to limit the number of open tabs.
Install via the chrome web store.
Automatically limit the number of open tabs.
If you end up with too many tabs open, all reduced to a tiny size, this extension will help you keep those tabs under control. After reaching a configurable open tab limit, that excludes pinned tabs, Tabalot will automatically close the oldest unused tab. As you get close to your tab limit, the extension icon badge count will start to turn red and will flash red when it closes a tab.
Note that the tab badge count shows tabs in the current open window only (which seems to be a limitation on chrome) but will correctly update as you switch windows.
