Over the last few months, I've noticed I'm getting a strange type of\npop up that covers the whole page with a somewhat opaque film, usually\nshowing a photo of sorts.\n\nI operate with my page color set to a more eye relaxing shade of light\ntan rather than the glaring white of most pages. This means I cannot\nsee where the dang OFF switch is to get rid of the pop up. My\nquestion is, what is this new type of PITA that someone has come up\nwith? I am using Adblock Plus and Better Privacy add ons with\nFirefox 3.6.13. What add on, if any, can I use to keep this nonsense\nfrom coming up and covering the page I'm trying to read?
