Edit Copy of this Filter

quasimodo,

go to your documents and settings folder in C: and into your account folder there and fine the folder, 'application data' and then 'Filter Forge'. find the 'My Filters' folder and open it up. there you'll see ALL of the filters in your 'my filters' folder of FF. simply make a copy of any you want and rename them there.

or, simply periodically make a backup of all files there in a backup folder so if you do have an accident you've got a backup.

i know that's not what you're asking for here and i like your idea of being able to 'copy filter' within FF. but in the meantime, this idea might save you some grief.
