An incredible addon, and I would give it a 5 star rating but for one thing — when you open the cache tab to copy something that isn't your last inputted text, and click the copy button next to the one you want to copy, it adds unnecessary formatting HTML code to what's copied, rather than just copying only what you actually entered.

If there was a way to make copying from the Cache page, rather than the dropdown menu plain text only, I would give it 5 stars.
