After reinstalling, a blank pop-up appears in the middle of the page, which has no copy and no way to delete, but it prevents taking any action on page.

Question

I had to restore my hard drive to a date two weeks earlier to eliminate an issue I was having. For some reason, this buggered my Firefox browser. I uninstalled it then reinstalled it (several times, now). It appears the reinstall is successful; however, when I open Firefox, a pop-up appears in the center of my homepage. It is blank except for a tiny box that I can check and uncheck and a grey bar in its center that doesn't seem to do much of anything. There is no copy in the pop-up. There doesn't appear to be any way to close it and it prevents me from from taking any other action including closing the page. Any clue what this pop-up is and how I might eliminate it? It doesn't appear with any other of my browsers.

Answer 1

I can't take any action once my Foxfire homepage is open and the mystery pop-up appears, which is immediately. I have to restart my PC to close Firefox because the pop-up prevents my doing anything connected to Foxfire. I can open other browsers or do other functions, such as open documents, but Firefox is frozen on the homepage. And, although I can move the cursor around the page, I can't click on anything.
