[Feature Request]: Add an option to show the current counter of opened links and total tabs opened in the browser

That would be useful.
Since the project seems dead for 4 years old;
I wonder if I should fork the repository and add this feature trough a pull request, but if I do I'll not be able to publish it on the mozilla extension's store because I'm not owner, you'd have to accept the pull request and update it, would you do that?

Also I'd like to implement #12
