Comment 9 for bug 310210

I checked out the Adobe Flash plugin - I had version 10.0.15.something installed.
After downloading the latest for Linux (10.0.22.87) and installing via debconf, it didn't seem to get installed. So I ran update manager and updated 309 various packages, one of which included the Adobe flashplayer and the package called flashplayer-nonfree, and restarting FF, by visiting http://www.adobe.com/software/flash/about/ it reported (via a flash frame, that required a
click to activate due to Flashblock - as you'd expect - and which was one Flash thing that always seemed to work) that I now really had 10.0.22.87 flashplayer installed, and it's now working again.

Hope this helps others.
