Do you have a 64 bit Firefox version, possibly from the repositories of your Linux distribution, or the regular 32 bit Firefox release?

The "/usr/lib64/mozilla/plugins/" folder stores 64 bit versions of plugins and links to plugins, so you may be missing plugins if you have a 64 bit Firefox version.
The "/usr/lib/mozilla/plugins/" folder stores the 32 bit versions of plugins.
So if you restore symlinks to plugins in "/usr/lib64/mozilla/plugins/" then you need to make sure to link to the correct 64 bit version.

Easiest would be to reinstall plugins and let the installer handle the symlinks.

hello, cor-el. Thank you for your patient answer, I really appreciate it. And I use fedora 17, Gnome 3 desktop, 64 bit, so I use firefox 64bit. I just want to know those linked libraries in the folder "/usr/lib64/mozilla/plugins/". If you use a linux based firefox( better in fedora), you can tell me what's in that folder. Thank you!
