Versions 10 through 19
Using 17.0.1 everything worked
What does not
Playing the webm video at http://www.mozilla.org/en-US/firefox/17.0.1/whatsnew/?oldversion=17.0 didn't run as smoothly as my native version firefox browser. It did a few "hiccups" and at one point it lost it's sound but after I reloaded the page the sound got back.
What was not tested
I didn't test any adobe flash videos
I tested playing a webm video with sound at firefox.org, worked fine but with a few "hiccups". HTML5 videos on youtube worked fine but with "hiccups" as I got when playing a webm video.
