Rated 4 out of 5 stars

Bluehell works OK, initially a few adds got through but I haven't seen one lately, the main issue for me though is that when I click a link from the the guardian today email to the guardian website, it blocks it and asks me to allow it, something I have to do daily. It would be nice if it had a remember my decision option, or else if it didn't automatically block webpages opened from links in Thunderbird.

This review is for a previous version of the add-on (2.0.1-signed). 

Sure, having a option to remember a domain could be a good idea and shouldn't slow down the extension - noted for the next version. Thank you for your review.
