I installed Firefox beta 9 and the flash plugin as a .tar.gz file. I unpacked it, installed it and now I can watch YouTube videos smoothly.
But I want to play mp3 codecs and other restricted stuff on my laptop. Should I uninstall the flash plugin for Firefox or just install the
ubuntu-restricted-extras package (which contains everything I need)?
If I install the package without uninstalling the plugin, will anything bad happen?
