Hi grandcapri, 
unfortunately this report is not very useful because it does not describe the problem well. If you have time and can still reproduce the problem, please read https://developer.mozilla.org/en/Bug_writing_guidelines and add a more useful description to this report by providing an EXACT testcase and describing what and (what not) happens.

I have the same problem.

Testcase:

1. Install Firefox 13 on fully patched Windows 7 64bit machine.
2. Install Flash 11.3 from Adobe website.
3. Go to YouTube website. Try to play a video.
4. Message "An error occurred. Please try again later" is displayed. Video does not play.
5. Go to BBC News website. Try to play a video.
6. No error message displayed. Video does not play.
7. Give up.

The Flash 11.3 does work in latest versions of IE, Safari, Chrome, and Opera... but not Firefox 13. It does work in Firefox 12.

David,
If you try following the instructions at http://forums.adobe.com/thread/1018071?tstart=0, does this help your Flash video play?

Yes, disabling protected mode does fix the problem.

Same problem exactly on two computers at home.  One computer a Dell Dimension 9100 the other an HP from Walmart, brand new.  Also will not play FLV video on my Dell laptop at work.  No problems with other browsers.  Uninstalled and re-installed and it still doesn't work.

There are lots of problems with the new Flash Player (version 11.3) Protected Mode in Firefox. 
Harpist, could you confirm disabling protected mode fixes the issue for you too?

I don't know how to disable protected mode.  I disabled add-ons...it didn't help.  It put it in Safe mode...didn't help.  Restored to original....didn't help.

I've resorted to Chrome.

Instructions on how you can disable protected mode can be found in the link from comment 3:

This looks like bug 763459.

Do you have the real player browser plug-in listed in Add-ons Manager-Plugins?

Followed instructions to disable protected mode.  Didn't fix problem.  Uninstalled Real Player.  Problem resolved.  This is annoying because I use Real Player. This is not a problem with any browser but Firefox. It should be able to be fixed.

I'll mark this a duplicate of bug 763459 - same issue with real player.

This is not a Firefox regression - it's caused by plugin conflict (Flash and Real Player-only occurs with the recent Flash version - 11.3). Some Flash updates might be available in the next period. I would keep an eye if those updates fix this issue.
