Videos that won't play, do work on other browsers like IE and Chrome so I'm assuming this is a Firefox issue

I have tried re-installing over and over again the flashplayer, i even tried rolling back to 11.3 but youtube still won't work in most videos it shows an error message saying "an error has happened please try again later"

I've tried some solutions posted before such as copying files from adobe's folder to firefox's plugins folder. but it didn't help either


I'm using windows 7 x64 firefox 16.0.1 Adobe flash player installed is (supposedly)11.4 but on adobe's check flash player version page, it won't show me the version instead a blank rectangle appears...(chrome and IE, do show it, however..stating that 11.4 is indeed the version installed)

Indeed, I had forgotten I installed RP long ago, just updating it seemed to be the cause of it all, thanks a lot.

I can attest to the suggestion about updating RP. I just did that and now magically all Flash player video works now.

There was also one suggestion to start Firefox in Safe mode (Firefox.exe -safe-mode), and then try to play Flash video. If it plays then you know it is a different plugin.
