Mac, OSX 10.6.8 (up to date), Firefox 28.0 (up to date). Adobe Flash was downloaded and no videos will run on any web pages using Firefox. I reset Firefox to default settings and restarted. I get the message that Adobe Flash has crashed. Shut computer down, rebooted. Same thing. Uninstalled Flash and the videos run but very choppy, jumping in 5 second increments after freezing. Firefox freezes and has to be force quit. Installed an older version of Flash and it will run, but I get a warning that it is vulnerable. I have gone through this several times and checked all my updates and they are the latest available. Videos do not run on the latest version of Safari either.

Glad to have helped. Thanks for posing back.

Remember to follow any progress, because hopefully a fix will be released and you do not want to remain on Flash 12 unnecessarily.

Downgrade to FlashPlayer 12.

I will add a link to a related post later. Flash 13 causes problems, and is a known issue with some older MAC s.

IF it is the same thing, as seems possible, it may be a known issue only affecting some Macs and the work around is to downgrade by using an uninstaller and reinstall the older versions

Wow, thanks John99! I spent a lot of time on Adobe's web site and could not find out anything at all about this problem or about version 12. I downloaded and it works fine. You helped me solve my problem in minutes vs the couple of hours I spend on my own. Thanks mucho.
