Essential Extension Rated 5 out of 5 stars

This extension is tiny, but essential! It is a very good addition to the built-in popup blocker! Now I have an icon in the status bar allowing me all the time to see whether this page wants to initiate a popup or not - without the annoying notification that comes down from top of the screen!

This review is for a previous version of the add-on (1.2.2).
