Forum:Firefox addons

Hi. I'm using DownloadHelper addon to help me hack youtube videos. I was thinking, is there any addon to more easely get high quality videos? Some of you might already know that adding &fmt=18 at the end of the url gives you a higher quality video even if there is no option to have it. I am looking for an addon that makes it easier to add this code, since I always forget what it was and have to search for it. I imagen a button in the toolbar that you can hit to add it. --Steinninn 23:15, 17 April 2008 (UTC)
