The page cannot be rendered error

Has anyone seen a "The page cannot be rendered" error when opening a PDF in Firefox? Seems to be limited to one PC, and Firefox has been used before. PDF was downloaded and appears normal. Other users can see the document using Firefox.

Maybe a simple setting that got whacked? v7.3 - cloud system.

Thanks,
