I am using a PC that runs on Ubuntu 16.04. While I was browsing the packages that have been installed, I found this one "account-plugin-facebook" (in addition to many other similar packages like account-plugin-flikr, account-plugin-google...) although I didn't install anyone of them.
My question is: What are these packages for? and can I remove them without any harming my PC?
Thank you.
This is a GNOME Control Center account plugin for single signon - facebook.
Which means it is used if you want to login to your facebook account via gnome. I cannot tell you if it can be uninstalled without problems as I use KDE and do not have such a package, but if you try uninstalling it and it does not try to remove a ton of other packages, you should be safe.
