Comment 25 for bug 326609

I upgraded from Intrepid 8.10 AMD64 to Jaunty 9.04 AMD64. Flash had been working flawlessly in 8.10 64 bit version. I was receiving the dreaded grey box where a flash animation should be in Firefox.

In my case flashplugin-nonfree was not installed (after the upgrade). I'm sure it was before. To be more specific when I ran:

sudo apt-get remove flashplugin-nonfree

It reported it as not installed.

In my case I just installed it using

sudo apt-get install flashplugin-nonfree

Restarted Firefox 3.0.9 -and flash plays fine. Hopefully it will stay that way.
