You have quite a line-up of Plug-ins (close to 30), some of them possibly superfluous and/or out of date, Please check if all your plugins are up-to-date. To do this, go to the Mozilla Plugin Check site.

Once you're there, the site will check if all your plugins have the latest versions. If you see plugins in the list that have a yellow Update button or a red Update now button, please update these immediately.

To do so, please click each red or yellow button. Then you should see a site that allows you to download the latest version. Double-click the downloaded file to start the installation and follow the steps mentioned in the installation procedure.

This may not be the immediate cause of the problems reported. However, it will make your system more robust and less prone to behave in a strange manner.

Thanks for the advice. I think I found the setting that may have caused the problem. But, some of those Plug-ins say Research which has been a problem in itself. When I opened Firefox again to reply to this. I got 2 windows. One with this page and one with my home page. I didn't set it up to do that but it does happen occasionally, which I had for gotten about. The window with the homepage has the Bookmarks toolbar while this one doesn't. Oh well, I will see how things go, and hope it gets better as I keep researching.
