There is a better alternative to solve the Flash High CPU usage on the Ubuntu Intrepid 8.10, using a possible official patch. This patch will generate a new .deb that can be installed and removed using the Debian’s Package Manager. To quickly install just follow the commands below on a Terminal (Applications -> Accessories -> Terminal).
sudo apt-get install build-essential fakeroot devscripts
cd /tmp
wget http://launchpadlibrarian.net/17178225/flashplugin-nonfree_10.0.1.218%2B10.0.0.569ubuntu1.debdiff
apt-get source flashplugin-nonfree
sudo apt-get build-dep flashplugin-nonfree
cd flashplugin-nonfree-10.0.1.218+10.0.0.525ubuntu1
patch -p1 < ../flashplugin-nonfree_10.0.1.218+10.0.0.569ubuntu1.debdiff
debuild -uc -us
sudo dpkg -i ../flashplugin-nonfree_10.0.1.218+10.0.0.569ubuntu1_i386.deb
This will generate a .deb and install it.
Update: patch was misspelled. Thanks Doug!

Nice post! I got this to work, however I used “patch” where you have “ppatch”. Thanks for posting this fix regardless! Now FFox is no longer bogging down on flash pages.
doesnt work for me. the command “cd flashplugin-nonfree-10.0.1.218+10.0.0.525ubuntu1” at line 7 returns no such file or directory
i don’t get it.. why not just put a .deb up here?
what worked for me:
remove ALL files from previous flash plugins (like libflashplayer.so and such)
install the version from adobe.com. (not the one from the repo!)
