I am not sure if this is a Twitter problem or a problem that for some reason Firefox is not allowing Twitter to read the info. When I set a background design the image doesn't show up. Now this is a new problem. Originally, for many many months, the design was there no problem. I uploaded a pic from my computer and it was there every time I logged on and refreshed the page. Then about a month ago it would not be there and instead where the design should be was simply blank white. Twitter still worked but no background. I would go to settings...design...and upload my image again and it would appear. But now I had to do this every time I logged in and if I refreshed the page I would have to upload the image again. Now yesterday none of that happens. Background is blank, I can upload image many times and it just never appears as the background. I am wondering if somehow where the image info or cookies for twitter or whatever are not being read from where the info is stored on my computer? I am hoping that some firefox setting is preventing the background from displaying because if the problem is on Twitter's end then it will never be resolved. Anyone have any suggestions at all???
