Three times in the last 24 hours, when starting Firefox, this window pops up: Subscribe to see EXIF info for this image (if available) It looks like a scam to me, as I have the latest version of Symantec antivirus installed. I kill the popup, of course, then Firefox opens to a window that shows a progress bar for a scan running. I kill Firefox and restart it again, and it starts normally. Has anyone else seen this? How do I get rid of this pest?
