Useful, but pop-up banner appears on wrong pages. Rated 3 out of 5 stars

The blocking function works fine. I've been using this as a blocker for ad sites, and it works quite well. Web browsing becomes much faster with a hard block on these sites. Here's a useful list to block:

*.doubleclick.net
*.quantserve.com
*.google-analytics.com
*.scorecardresearch.com
*.gravatar.com
*.247realmedia.com
*.likeme.net

The only problem is the annoying banner that appears when a site has a blocked ad. Not only does it appear on the page where content is being blocked, it also appears on other pages that happen to be open at the time but don't contain blocked links.

This review is for a previous version of the add-on (0.7.1.1.1-signed.1-signed).
