NoRef

BPPlugins

NoRef allows you to quickly copy your current URL while removing unnecessary and potentially very long referral data (ex. ?ref=123). You can set your own key macro of up to 3 keys to copy the URL without referral, or in the cases of some sites like YouTube where referral info is needed you can set a key macro to copy the entire URL. NoRef also stores all of your recently copied URL's (on your local machine, not in the cloud) and you can delete them all or just certain ones.
