Review for AutoCopy by itchy79
Rated 5 out of 5 stars
First, follow the instructions in this link: http://jerryfardons.blogspot.com --you'll have to download 7zip (freeware) in order to open the .xpi file.
Then, once it's installed (you'll need to tell Windows to open the file with Firefox), go to the options and UNCHECK the copy as plain text option -- because that hasn't been updated for FF 3 yet (if ever). Restart the browser and Autocopy will work as great(ly) as ever.
