Rated 5 out of 5 stars

I used to use RefControl which in comparison is old unreliable.

This though works well and is sensibly done, it lets you specify both source and target URLs and works reliably, though a rather simple little addon referrer control is important to me and this one seems to have no flaws so far.

This review is for a previous version of the add-on (0.4.2.1-signed.1-signed).
