Cannot reinstall an extension
Until a few weeks ago, I had the McAfee extension installed. It is now no longer there and when I try to install it, I get the error message : Firefox could not install the search plugin from "https://addons.mozilla.org/firefox/downloads/latest/256701/addon-256701-latest.xml?src=addondetail" because an engine with the same name already exists.
How can I delete the old copies of McAfee?

That is a search engine.
See:
This answered my question on why I could not add the McAfee plugin. After deleting the search engine from Firefox by using "manage search engines", I no longer got the error message that the engine already existed.
However, the plugin from Firefox did not do what I previously had before McAfee stopped working on Firefox.
By going to McAfee's website: http://home.mcafee.com/store/free-services I was able to put the extension back into Firefox and things work the way they did prior to having this problem.
I believe what might have happened is that this McAfee extension was not carried over during an update of Firefox.
Thank you very much for getting me going on the right track. I had worked on this problem for over a week and your input led me to resolving this in minutes.
