I have the same Mac book Pro OS X 10.6.8 and since the last update of Adobe Reader I am unable to view any documents with (application/pdf object) at the end of the name. I am using Firefox as my browser however the problem does not seem confined to my browser. As a student studying Distance Education this is proving to be quite a problem. I couldn't open my marked assignment posted back to me on Monday. I also am having trouble opening lots of readings for my course that just open to a blank page.

What is the solution?

Launch Firefox now and try to open a pdf. This should work

For Safari,

Please launch your Safari in 64 bit mode and then try viewing/printing the pdf. We don't support Safari 5.1 in 32-bit mode.

In my case, the problem occured only when I used Firefox.  I followed your advice in that regard and retried opening several pdf's that previously would not display.  All did display in 32-bit mode for FireFox.    Your statement that "We don't support Firefox in 64-bit mode."  and your self-description as "Emploee" lead me to think that you are an Adobe employee.  I'm new to all this, so sorry if my inference about who you are is wrong.  But if it is correct, then your advice would seem to be from-the-source-credible.  I hope that in the future, Adobe will support Firefox in 64-bit mode. 

One question though:  If, as you state, Adobe does not support Safari 5.1 in 64-bit mode,  why haven't I had the same problem displaying pdf's with version 5.1.5 Safari?  Only guess I can make at that is that as of Safari 5.1.5 (vs. Safari 5.1), Adobe does support Safari in 64-bit mode.  Anyway, thank you!  And I hope that in my newness to all this, I haven't confused things too badly.

Hi Oliverka:

I tried that and it did not work at all. I cannot open PDF's at all using Firefox 12.0 for mac and Safari too. I did not cahange any settings. Must be an update. What is the next step???

I uninstalled Adobe Reader 2 times. Nothing. I changed the Preferences in Firefox to ASK all the time no good. went back to Reader as the default Adobe Acrobat FDF Doc Setting?

So frustrating!!!! Please help me anyone I really need to use the PDF's on the Web for Real Estate.

It works!

I disabled the plug in and I can now view the PDF's.

Thank you so much.

See my post at the borrom of the thread.  Basically, here are the steps that worked for us:

Go to the hard drive--

Then Library--

Then Internet Plugins.

At the top of the list are two Adobe plugins.

Delete those.  Restart the browser.

Hope it works for you.  Now my brother has the problem as well.  I hope someone at Adobe is reading these forums!!

Did the Adobe Acrobat plugin formerly support these browsers?  Now the latest update causes users to change unrelated system settings just so they can still view PDFs when they click on links to PDF files.  A nightmare for IT management.

Also note that after this update, you cannot print PDFs from Safari by clicking the usual File->Print.  Most people are better off using the built-in PDF viewers of the browser (in Chrome or Safari), or http://www.schubert-it.com/pluginpdf/, which seems to work better than the Adobe plugin itself.

From Princeton University's "Issues and Quirks" page:

Please fix these aparent problems in the next update.
