Flash Video problem: full screen doesn't work

[Nuu]

There seems to be a problem with flash streaming on Firefox (and Epiphany, which I tried as well, with no luck). Although it works fine on some sites, like Youtube, on others, like iView, pressing the full screen button does nothing. I tried disabling hardware acceleration, but that does not appear to be the problem.

Does anyone know what's wrong?

Sorry, but I really don't know what to do. I'm no computer whiz.
