Rated 5 out of 5 stars

With this addon it's easy to protect your privacy and send the Referer-Header only to a list of websites which wouldn't work without it. The referrer for all other websites is blocked. Never again switching by hand with "Modify Headers" or the like (and forgetting to block the referrer afterwards) is needed.

This review is for a previous version of the add-on (0.8.10).
