Automatic referral extension

Today I found out from a comment that there is now an Firefox Greasemonkey extension for adding referrals to comments. That is... a script that writes automatically whether the photo was seen in a group or in the user's photostream, or homepage. Great! :)

Has anyone heard of other Firefox extensions for Ipernity? (Other than the Flickr-to-Ipernity one)
