Comment (by dcf):

 Replying to [comment:2 CRhode]:
 > Would previewing *.pdf files in the Firefox Document Viewer raise this
 condition, too?  That's what I'm seeing.  TOR complains that my Website
 "attempted to extract HTML5 canvas image data."

 I saw the warning with PDF files in 3.6 too. I think the warning on image
 hover is new with 4.0.
