Great add-on, only has 1 issue:
Blocking of duplicate password-prompts also blocks messages such as those related to blocked website pop-ups.

Update:
Indeed the yellow pop-up example: http://www.popuptest.com/popuptest3.html

This review is for a previous version of the add-on (1.16.1.1-signed).

Are you referring to the yellow "popup" on to of the page?

Any websites to test it on?
