Install Flash Player 10 in liferea
Caveat lector: I wrote this post in high school; it’s likely outdated and poorly written.
Installing flash player 10 in Ubuntu does not install it for Liferea.
The fix for this is very simple:
First install Flash Player 10 using this Tutorial
Next execute this command in the terminal:
sudo ln -s /usr/lib/firefox-addons/plugins/libflashplayer.so \ /usr/lib/xulrunner-addons/plugins/libflashplayer.so
Flash Player 10 should now work in Liferea.
