Did you install an extension for exif viewing? Go the three dots in the upper right corner, then go to Settings - Extensions and see if there is an exif viewer installed.
Maybe I misunderstood the question, but I thought Nikonpup was unexpectedly seeing exif at the top of the screen (or notifications that none was available.) So I thought maybe he inadvertently installed a photo analyzer plugin that was showing him this info as he moved his mouse around.

I found that if I post my photos centered instead of oriented to the left that the EXIF data goes to the top out of the screen on this site. Post to the left and the exif data shows up in the shot when using mouse over. I still haven't figured out how to get by the Capture Date being stripped from the exif data on this site.
