If you are running Flash v 9.0.115.0 with Firefox 2.0.0.1.2 on Windows XP there is a chance that Flash is not working properly. You will know this because Flash videos (youtube, etc) will play for about two seconds, with no sound, and then just stop. Flash will function normally in Internet Explorer though. This is a problem with Flash. The word is that it should be updated with the next version. If you want the full explanation, read this thread. I just did, and I don't recommend doing so. If you want the fast and dirty way to fix it, here goes: 1) uninstall flash 2) install flash 9.0.47.0. Here is the page if you want it... 2a) you'll have to reinstall Flash again for IE (but now that Firefox works properly again, you won't really need IE will you?) That's it. Flash should work, but you will have an old version. When the next version comes out you might want to muster up the courage to upgrade, but bookmark this page just in case. 10/10/09 - UPDATE- If you are still having this problem, especially if you are using Firefox 3, then upgrade to Flash 10. This should solve almost all problems and it seems to have fixed my Flash issues.

Did you just upgrade your Flash player and now it won't work? Or you upgraded and it works in IE but not Firefox? Or how about you uninstalled it via Windows Control Panel, but it's still there? Yeah, working with Flash is not as easy as it should be given its ubiquity. This is why people don't upgrade, despite security flaws or don't install it in the first place or block it. Is you are having problems with a recent upgrade, probably 9.0.115.0 then here are the links you need:
