Why versions in double or more of plugins/addons appear on startup?

I recently started using CCCleaner and performed an analysis of all the plugins and modules that are enabled for the start-up on FireFox. Interestingly, many of the old versions of certain modules and plugins appeared and are enabled. In addition, several same programs appear several times. Is this right? Can older versions of the plugins/Add-ons disabled?

The following is a copy of the dubious elements of my most recent analysis. (I removed my name from documents and settings, for personal reasons):

You are welcome

It is always better to uninstall obsolete extensions or defective instead of disabling (Firefox will still check the updates).

If you can't remove an extension then it is installed in the world and you need to remove this through each program that added them.
