As far as watching subbed anime goes, I tend to go to Animeseason first. However, lately, it's becoming rare that any of the videos will actually appear there. If the video comes from a site that NoScript blocks, the space for the video will be there, showing that it's blocked. Once unblocked, that space vanishes. Even if the video had never been blocked. It seems like the video appears for a split second whenever I click on a tab (which chooses the location of the video), as if it wants to appear/work, but then doesn't. I just checked it with IE, and it works perfectly fine...
So, yeah, I don't understand what's wrong. Is it the site? Does Firefox need a certain plug-in?
