Rated 5 out of 5 stars

It's very good, and simple.
I "block the referer" for every website and i whitelist websites that i must so they can work properly.
But i experienced a few cases on some websites, when unblocking the referer didnt work, and i had to turn off this addon. I don't know, maybe it's because of how the website work... :-|

This review is for a previous version of the add-on (0.8.16.1-signed).
