This del+reader script used to be my favorite of the bunch. The ability to add your own tags for 1-click saving actually was the main reason I switched from Camino to Firefox (helped by FF3's massive speed bump).

Alas, these days are over. The script no longer works. In fact most of the others don't work either (since g.reader's update). The only one I've found thus far is right here.

Here's hopin' ya come back, dear friend.
