You probably leaved it where it is and never used it anymore; but listen!
Facebook Video Calling installer places a scheduled task,
FacebookUpdate, that is launched every 10800 seconds (3 hours), by the "tasks manager" used by Mac OS X:
It checks for Facebook Video Calling updates and probably sends informations about your system to Facebook servers (read Facebook is "Peeping" into Your System).
Why to waste CPU time (even if a very limited amount) and Internet bandwidth, to periodically check for updates and eventually download an update of a software that you will never use anymore?
The Facebook help page explanation is quite "simple": How do I uninstall the video calling plugin from my computer?.
Don't worry! I am here to help you. :-)
The first thing to do is to unload the job that periodically runs
To do so, open the Terminal application and type the following command.
launchctl -w ~/Library/LaunchAgents/com.facebook.videochat.your_user_name.plist
This will tell to permanently unload the job from the
launchdlist and the job will be never loaded anymore when you login in to your Mac.
launchctl remove ~/Library/LaunchAgents/com.facebook.videochat.your_user_name.plist
This will permanently remove the
plistconfiguration file from your file system.
FacebookUpdateapplication is running (not very probable) you can stop it using Activity Monitor application. Open it. From the "View" menu choose "All processes" and type "facebook" in the search text field. If the process is running, it will appear in the list. Select it and click the X button on the left of the tool bar to kill the process.
Now you can remove the files installed in the system. Go to
~/Library/Internet Plug-Insand remove the
FacebookVideoCalling.bundlealias by pressing COMMAND-BACKSPACE or dragging it to the trash.
~/Library/Application Support/Facebookand remove the
