Flash Player Glitches

Removing Conflicting Plugins

Ubuntu comes with swfdec plug-in, but it doesn't work on several sites. Installing the version from Adobe might solve this problem and improve performance.

To remove other flash plug-ins and install only the one from Adobe open "Applications >> Accessories >> Terminal", then paste (CTRL+SHIFT+V) the code below in the terminal window and hit enter:

sudo apt-get remove swfdec-mozilla
sudo apt-get remove mozilla-plugin-gnash
sudo apt-get remove adobe-flashplugin
sudo apt-get remove flashplugin-nonfree
sudo apt-get install flashplugin-nonfree

Flash Tweaks

If you're still encountering problems, try:

sudo mkdir /etc/adobe
echo "OverrideGPUValidation=true" >~/mms.cfg
sudo mv ~/mms.cfg /etc/adobe/
