flash video does not work everywhere

[ratcreature]

I can watch streaming video, but some sites, like for example The Daily Show have stopped working. Not so long ago (i.e. like last week), I could watch that. On other sites it still works, like for example I have no trouble on youtube. But on the Comedy Central page it now says "To view this movie you need the Adobe Flash Player plugin. You also need JavaScript enabled in your browser."

So then I figured maybe I need to update my flashplayer, and tried first the stable one, then the beta (my current player version is now 11.2.202) but neither helped. Then I wondered whether maybe some of my other Firefox additions caused trouble, that maybe some script or adblocking interfered, and I hadn't allowed all the necessary scripts, so I allowed everything for the page in NoScript, disabled Adblock and Ghostery blocking, but it still doesn't work. Then I tried another browser entirely, and went to the site with Epiphany, so no add-ons could cause trouble, but again flash video worked in principle, but not on the Daily Show page. :(

Any ideas what the problem could be?

ETA: I changed absolutely nothing, and now (on March 1) the video plays again. Maybe something was wrong with their site setup. Odd.
