When starting Firefox, stops & asks for Chome plug in

Recently Firefox stops its opening sequence as it says it needs a "Chrome" plug in?
Whatsup? I do not have Chrome installed. I have no idea why Firefox wants a Chrome plug in installed.
How do I eliminate this annoying request?

 

NO, that's part of anoyance. If it did, I'd say no if I could.

 

I had never heard of a Chrome plugin until I did a search, and, pretty much as expected there is an add-on which allows one to view in Firefox with Google Chrome engine, very much like there is an IE Tab add-on to view with the IE engine. I would expect that Google Chrome should be installed for this thing to work. Beats me why the nag would continue, but possibly there was a check mark if Google Chrome was installed, or a certain website visited. Firefox has two Chrome folders, one in the program, and another one in the profile, but this is an entirely different beast.
