I normally will use Safari because even now while Firefox, there is a lag between what is typed and what appears on the screen. When I pull down a menu or try to add a bookmark, I have to click on the field at a certain time because the text field is moving side to side. I am unable to capture this effect and copy and paste below. Safari browser does not do this. Some of the sites require that I have Firefox or a more recent browser. I cannot run Google Chrome on my Mac because it is not Intel based. Thank you for your assistance. == This happened == Every time Firefox opened == After I started using Firefox. This has been happening for a while.
