AskUbuntu Add-on

This extension displays user reputation/badges, monitor activity and provides an easy access to unanswered questions, user questions, user favorites and user tags from an askubuntu.com account.

The extension preferences allow to specify which category of questions will be tracked and how many items per category to track. New activity is identified by colored icons and each question can be manually marked as read or by visiting the link. You can also hide items you don't have any interest and specify the update frequency.
