May someone please help me...?

My guess is you downloaded a phony 'urgent FF update needed" from an orange screen which was NOT a mozilla site. With the possible adware or malware or ??? running (or hooks someplace), what you type in may not be going where you would expect.

Since no one has picked up your question, I'm offering those possibilities. What ever your password is on that 'target' account, I suggest you use another browser and change it.

This is just 'chicken soup' (it could help and couldn't hurt.)

There are too many possibilities and I only come here once in a while,so I not a good volunteer to help assertain what the full story is.

There are lots of bad people on the Internet writing programs and trying to get information (as well as millions of dollars) from people. Or it could be something simple.

But just because you are on the latest FF release (top left 'help' then 'about Firefox may not be a totally safe situation. Too many possibilities. I look for excessive CPU activity, new programs shown in Task manager (control-shift-delete)

Bear in mind I do not use Google Notifications and my paranoya (sp?) may be totally unfounded. Or there could be something simple. Have you searched this site or a search engine (such as duckduckgo) for someone else who has the problem? Or google itself (although that may not be easy or fun. LOL ) Perhaps rephrasing the question might zero in on someone elses report.
