It's a fun little extension but it'd be better if it remembered your replaycements and used them when you refresh or load new pages.

It's really good to prank friends and do something when you're bored. I would love it if the changes didn't clear if you refresh the page, but there would be a clear changes button along with the replacing text boxes.

WebExtensions, here we come.
