To the appropriate person I have used the Firefox browser for many years. And will continue to do so. I have been given a challenge. The Firefox browser refreshes the websites several times just as it reopens the page again and again. The mouse pointer chops across the screen. It all started within the last week. Is it a setup error or an update that didn't go as it should? I don't have the same problems with Google Chrome or Microsoft Edge. Kind regards KlausW
