Good addon Rated 4 out of 5 stars
Gets more useful the more you use it. Watch for program updates, postings etc.
The latest update has removed the feature where pressing the toolbar button used to immediately open the SiteDelta sidebar. Now you seem to either get a menu or it scans the page you are on and then monitors it in the future STILL without showing you the sidebar with the list of sites. This is NOT an improvement.
