For long I have been having problem with flickering flash videos in the Firefox 4 beta in Ubuntu 10.10 64-bit. Today I found a solution, and I have no longer any reason to use Chrome.
It seems that the problem with flickering flash videos only occurs with Adobe Flash Player 10.1. So, by installing the beta 10.3 of Flash Player, the problem is now long gone.
I don’t know how you install the Flash beta in the 32-bit version of Ubuntu. But in the 64-bit version you just need to type these lines in the terminal:
sudo add-apt-repository ppa:sevenmachines/flash sudo apt-get update sudo apt-get <a title="See also Ubuntu - How to Install MKVToolNix (Matroska tools) in Linux" href="http://www.whileifblog.com/2012/02/21/ubuntu-how-to-install-mkvtoolnix-matroska-tools-in-linux/">install</a> flashplugin64-installer
I hope this solution works for you.
