The following appears to have I solved my problem with Safari 5.1.5, 5.1.6 and 5.1.7. I also have Adobe Acrobat Pro 9 installed.
- Follow mbuffy's post dated May 10, 2012 directly above, and
- Do NOT allow Adobe Acrobat Pro 9 to perform the "repair" the missing Adobe PDFViewer Plug-in when the window pops up and offers to repair Adobe PDFViewer Safari Plug-in. If Adobe does the "repair," then I can not view .pdf web pages in Safari or Firefox.
FYI, cmmartin0275 posted the following on Sep 8, 2011 in a discussion of "Missing PDF Pluggin" at https://discussions.apple.com/message/16119130#16119130:
"Just FYI to anyone with this problem...this is straight from Adobe's website.
"Adobe Reader plug-in and Acrobat plug-in are not compatible with the Safari 5.1 browser, which will ship with Mac OS X 10.7 and for 10.6 in July. Adobe Reader and Acrobat will continue to work as standalone applications on Mac OS X 10.7 and 10.6, and will render PDF documents outside of the browser. In addition, Safari 5.1 renders PDF documents natively. However, the Adobe Reader and Acrobat plug-ins will not function as expected in LiveCycle and Acrobat workflows that require either plug-in to render PDF documents in Safari 5.1."
They also go on to say they hope to have a solution or work around before the end of 2011..."
Thanks for the help.
FIXED! Evidently, neither has fixed the issue as it's now July 2012. Following mbuffy's post, I moved the PDF plug-in to the trash, and restarted. The black PDF pages issue was resolved. Prior to checking here, Adobe tech support told me Safari was at fault, basically of no avail. If folks are having the issue with other browsers, then D'OH! Never had the issue prior to installing CS6. I may have mindlessly clicked OK to something while installing. In addition to dumping the plug-in, I also uninstalled Acrobat Pro X just in case. So thanks to all. I'll be back if the issue returns after I re-install Acrobat Pro X, but will keep in mind not to accept the repair PDFViewer plug-in message.
