TabCounter is a Firefox extension for people who are tab addicted.
If you often find yourself wondering how many tabs you have curretnly open, how many tabs did you ever opened, and what was the max number of tabs you have opened at once, this extension is for you.
TabCounter adds a simple unobtrusive panel at the status bar which shows you the current number of open tabs. If you have more than one window opened, it display the information for the current window and a sum for all windows!
The extension also provides some stats about your tab usage. If you click on the extension’s icon, you can view information about your record, record date and average number of tabs opened. This information is available both for the single window and the all windows counters. You can also view the number of total tabs ever opened!
The extension is currently available in the sandbox part of Mozilla Addons site, and you can install it if you have an account there. Soon I’ll be updating the extension with more features (more fancy stats!) and after that the extension will be in the public part of the Addons site.
If you have an account at addons.mozilla.org, you can install the extension here: https://addons.mozilla.org/en-US/firefox/addon/6391
