Are you tired of manually switching between tabs to see if you have new e-mails, messages, or items in your RSS feeds? Then say goodbye to the hassle! Tab Badge adds an awesome counter badge to your tabs and lets you see the number of new items with just a glance.
Tab Badge displays equally well whether you have a tab set at full size or pinned as an app tab. As you can see above the badge really stands out and the text is easy to read.
Installing the add-on does not require a browser restart, so just click and go to start enjoying that tab notification goodness!
Note: Works with Firefox 4.0b7 – 4.0.*
