As of yesterday my screen has gone black. Not on all sites, my homepage is a UK news site and that`s OK but my email is all black, when I try to search for a new sight the google page is black. Some sites come up black and some white. Sometimes the site background is white but the drop-down box is black. I have tried disabling all add-ons it makes no difference. I have tried un-checking these boxes: "Use recommended performance settings Learn more These settings are tailored to your computer’s hardware and operating system. Use hardware acceleration when available" I am demented and have tried fiddling about for a whole afternoon to try to sort this. I have had Firefox for years and have never had this problem. My version is 95.0 (64 bit)
