Some random websites will not open,instead showing "Gif.pic,1x1"
On a totally random basis ( at least I have not seen a pattern), when I click on a link to some websites, a new tab opens with "Gif.pic, 1x1 pixels" but a blank page is all that is displayed. There are no other error messages or fill information or bars displayed - just that tab heading. I cannot list the URLs because it has happened so randomly. However, just a few minutes ago that is what I got when I tried to open two of the Mozilla sites returned from a search.
