This is not a reply to my own question, but additional information that includes a screen shot of what it looks like after I click on to see if my plug ins are up to date. As you can see, the listing of plug ins is missing. Thank you.

I clicked on: "Check to see if your plug ins are up to date" and all of the plug ins that I normally see are not listed at all now. I do not see any plug ins. I did not have this problem until today, and don't understand what happened. I appreciate any help that someone can provide. Thank you.

This is not solved!!!

hi linda, this is a known bug on the website which is going to be resolved later today. the mozilla webops is working on it!
