Comment 44 for bug 98688

 Bugmenot's solution worked perfectly for my system. Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.8.1.3) Gecko/20061201 Firefox/2.0.0.3 (Ubuntu-feisty)

                 had the same problem with debian. my solution:
                 uninstall any current flash package (flashplugin-nonfree or flashplayer-mozilla)
                 get latest version (with MPEG4-AVC support) from adobe-labs:
                 http://labs.adobe.com/downloads/flashplayer9.html

                 i got the rpm and converted to deb (sudo alien flashplayer9_install_i386_082207.rpm)
                 installed it with "dpkg -i flash-plugin_9.0.60.184-1_i386.deb"
                 sudo /usr/lib/flash-plugin/setup

If you are a little confused follow this:

   goto http://labs.adobe.com/downloads/flashplayer9.html

   right-click Download Plugin for Linux x86 (RPM, 2.88 MB) and save as to Desktop

   close browser
