Rated 4 out of 5 stars

As others have mentioned, this would be much more useful if it controlled the referer FROM sites (e.g. indexing sites), not just TO sites. I use this on Google Images to stop sites from blocking direct image links, but I have to use the " (3rd Party)" option, which breaks functionality on a LOT of other sites. When something doesn't work on a site, it's often (but not always obvious) a referer problem. I've already had to add 20+ exceptions because of this. It would be great if I could have just ONE entry for images.google.com and leave everything else set to "Normal".

This review is for a previous version of the add-on (0.8.12).
