Rated 5 out of 5 stars
One of the best extensions out there. This is now part of my standard "can't browse without" package that I install whenever I create a new profile. The combination of copying by selecting text and pasting the clipboard via the middle mouse button is as brilliant as it is simple. Thanks to Mr. Lidman and Mr. Ochtman for making a fantastic script. This really should be implemented as an option in Firefox.
@Lee Dailey: If you find this script is working "exquisitely well" on FF an TB even when it's not supported on the latter, how on Earth does that experience constitute a 4/5 star rating?
