I have a slow broadband connection (256k) and YouTube plays okay with the 240p quality, so I always select 240p.
I've also ticked the "Never play high quality" checkbox and it stays checked. The current video then proceeds to load in 240p but later on, the YouTube videos always revert to 360p (when I change videos or refresh the page, etc.).
How can I fix this? I don't want to be selecting the 240p from the controls bar every time.
