Review for RefControl by Mozzyy
Rated 1 out of 5 stars
Basically useless as it still seem to only block referrers TO certain sites and doesn't offer any way to block referrers FROM certain sites.
The reasons why it 'should' work like this are many, even the site for the addon lists such reasons, maybe just doesn't realise it, yet this still doesn't let you hide the referer in a useful way.
While it does let you block all referers which is a small saving grace it doesn't have a whitelist so again falls short.
To create your own collections, you must have a Mozilla Add-ons account.
