Hi jmooore733- According to this Adobe site, Flash player 11 should be compatible with Vista:

I would recommend going to this article:

https://support.mozilla.com/en-US/kb/Managing%20the%20Flash%20plugin

There you can test to see if you have the latest Flash player, and upgrade if necessary.

Hope that helps!

You need a 32 bit Flash version for the 32 bit Firefox version.

You already have Shockwave Flash 11.0 r1 installed according to your plugins list and it should work on Windows Vista. What do you see when you try the Flash Player test link?

You said, I get the message 'this video is no longer available' when you try to watch videos. Is that the complete message and do you see it for all videos you try to play, for example, at YouTube.com?

You also said that you cannot find access to previous versions. The Adobe Flash Player forum has links to Flash 10 for Windows, here:

...but before you try reverting to Flash 10, see if this Adobe article is helpful:
