I made a typing mistake while using the Firefox web page, made a typing mistake, and tried to backspace the error. However the Firefox window spun around on the screen a couple of times, then stopped.
I wasn't able to see it happen again. I am running version 19.0.2
Have you seen this reported before? Do I have an issue with a virus? I am running McAfee Security SiteAdviser, and it is current. It did not find an issue on its last scan.
may be it's a malware issue you can checkTroubleshoot Firefox issues caused by malware
Thank-you for the information. I don't go into questionable web pages. The last web page I had looked at was the London Gazette and was looking at information from WW2.
I had checked McAfee SiteAdvisor before entering the site, and selected a link to view a list of published medals (070409 Medal Start Dates.doc).
I haven't had the issue again - I ran a full scan after it happened. I will contact McAfee Support and see if I can verify that my Security software has not been compromised.
