I managed to resolve this by removing all the extensions in Chrome, Firefox and Safari.
Settings (upper right side) > Extensions > Remove Photo-zoom (I removed others that i'm not using just to be sure)
Settings (upper right side) > Extensions > Disable Photo-zoom
File Preferences > Extensions > Remove Photo-zoom (I turn off everything)
Hope it helps.
Safari Photozoom extension?! this thread has the best and most legitimate explanation on how to remove it before you all go in and start deleting things that you might actually need like I probably did. this is the actual uninstall method. thanks again carol!
