I began using CoLT (Copy Link Text) a short time ago and it now feels like a natural part of firefox. There are a number of times in my day to day work where I need to copy the text of a hyperlink and without this extension it is challenging mouse work to get it right. With this extenstion, I simply right click on the link and select “Copy Link Text”. I then have exactly what I want on the clipboard. I highly recommend CoLT.
