When I try to watch any movie, it just say "This video is not available. bla bla bla Flash needed or browser compatible with HTML5". I guess it's something related with browser, since it won't recognize it as Firefox.

Btw, the video works normally on Firefox (28) and Chrome.

What can I do?

A fast fix is to go to 'about:config' in you browser an find 'media.windows-media-foundation.enabled' and set it to false.

The OP is on the Linux platform, so the Windows prefs media.windows-media-foundation.enabled and media.directshow.enabled won't help.

On Linux there is the media.gstreamer.enabled pref to disable MP3 and H.264 support.
