"I am visually impaired'' and am having problems with this new update. My unread links have all gone florescent blue (rather than bold black for unread and unbold black for read); to my eyes, they flash and I can't read them. There are no lines around the tabs so I can't tell where I am. On web pages, many of the outlines have disappeared. Setting my preferences and telling Firefox to always "override the colors specified by the page" doesn't work. And it's not a virus or my computer. Safari uses bold black for unread links and unbold for read; Safari is one of the least visually accessible browsers I've ever encountered. Firefox was visually accessible for years. What gives? Help please.
