Can we get a screenshot of the issue?

Thank you very much for the reply. The attached image is one of several which appeared briefly in the lower right-hand corner when I started up Firefox this morning. There were several, one after the other. Often, "clicking" on the message does nothing. Thank again.

Thanks for the reply Dropa. This is a cropped image from the lower right corner of Firefox. These images only appear when Mozilla Firefox is opened, I believe. However, I'll double check tomorrow and get back to you.

As additional information, attached is a screen shot from when I opened Mozilla Firefox this afternoon. This only occurs when Firefox is open and occurs within the Firefox screen.
