Loading a video in firefox seems to be very unreliable for me, a lot of the time it will get stuck on a loading video animation or something, but no video.
This happens on all video sites, but especially seems to happen on Youtube (doesn't seem to so much on iPlayer, but I use Youtube a lot more often).
Clearing private data and refreshing the page usually works, but sometimes it needs to be done twice and it gets to be a pain when you have to do it on every video.
It seems to work much better on Opera in ubuntu or on firefox/chrome in windows, but it's a pain on firefox in ubuntu.
