Hi ScottWitte,

Have you looked at our Flash plugin troubleshooting section? There is a lot of useful information in there that should help you get to the bottom of your issue.

Hopefully this helps!

Hi!

That's not normal. I tried to run a couple of videos and it works fine for me.

Have you tried to run your browser in Diagnose Firefox issues using Troubleshoot Mode? I suspect that an add-on is messing up with your browser and Flash configuration.

Matt & Ibai,

Thanks. I tried a number of the suggested solutions earlier but missed the idea of running in safe mode. Duh!

Doesn't help. Strangely if I just aim for a temporary disable it doesn't seem to take. Flash should be turned off as an extension and it isn't. The add-ons manager still lists all add-ons as enabled. So I disabled all add-ons "permanently". Now Flash failed to load, of course. Went to the add-ons manager and enabled just Flash and.... Crash in Vimeo, not elsewhere.

Restarted again in Safe Mode. No difference.

Try to disable the hardware acceleration in the Flash Player.

See:

• http://www.youtube.com/swf_test.html (right-click the player: Settings)

Flash "Display settings" window:

Cor-el -- Thanks for the suggestion. It is logical trouble shooting but unfortunately has no effect. Vimeo video (no others) crash Flash whether HW acceleration is enabled or not.
