Um.  That's not the problem, because I could go into Safari and use their onscreen tools to download and view.  Apparently this all happened in the last update for Firefox for Macs.  This is how we fixed it (courtesey of our Mac tech on campus):

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.

It should work fine now.

Again.  There were no error messages.  There was just a blank page and no action in the downl

Do you have Adobe Reader or have you purchased a version of Adobe Acrobat?  If so which version?  Also which operating system are you using?

Hello

I downloaded Adobe Reader and I have a MAC (Lion). I used to be able to

open PDF with what I have and then all of a sudden it stopped working and I

have to save them and then open them and sometimes it works and sometimes it

doesn't so I am not sure what happened. Do you know what could have

happened?

Moving this discussion to the Acrobat Installation & Update Issues forum.  If you could also please respond with the error message you receive when you try to open your PDFs?

I have tried some solutions -- like putting Firefox in the 32-bit mode

I use both Safari and Mozilla on my MacAir OS 10.7.3

Tried to download Adobe Reader (although it's supposed to come with my purchased Acrobat 9 XPRO), but I get eh message that "another instance of Adobe is running...." but there isn't.

Obviously this is a problem for many....but Adobe hasn't offered any help other than to go to this forum -- but there isn't any clear cut solution?

By the way, I decided to try opening the pdf files using my old Dell (for which I bought the Adobe Creative Suite 5 Design Premium) and I am able to open pdf files using Mozilla Firefox

So the problem isn't with Firefox...

The problem is how Adobe works with the MAC. And for my MACAir, I bought the Acrobat Acrobat XPRO

So I truly expected to get some help from Adobe since I did buy the product and not mrerely downloaded a free software instead of being referred to the forum to try and find a solution for a problem they created.

I'm having the same trouble, as is my husband.  Downloaded latest Adobe update--and PDF files won't download.  Actually the download window doesn't even function anymore, but it's probably because I'm not able to download anything.  No error message.  Just. . . nothing.  Firefox is the browswer, Lion the OS.  When in Safari, I can access a small menu when I click on the PDF image which will then allow me to save it.  But nothing with Firefox.  Husband contacted his Mac specialist on campus (we're both educators) and he said to access the root level file and remove the Adobe plug-in and then go back to Firefox and install the PDF viewer, but I can't replicate that on my machine.  (Root level?  Really?)  Sounds like a problem.  Can you fix it?

Hi,

Is there someone I could speak with to get this issue resolved for me, as well? I have been contacting different sectors of Adobe's contact line, have tried fixing the issue (not being able to open PDF files) myself, have tried looking on the internet and cannot find any sort of solution. Is there someone I could speak with directly so that I can start viewing PDF files?

Not sure, but I read some of these posts and may not be exctly what I am experiencing.

I using a mac with all the lastest updates.

I have version 11.0.03 of Adobe Reader

When I use Safari to view a .PDF file, I can view it with no problems.

The problem comes after I SAVE that file.  So when I'm viewing a site such as http://www.lightroomqueen.com/downloads/shortcuts/lightroom_shortcuts_40_mac.pdf and then in Safari I go... FILE>SAVE AS...and select that default file name with it's .pdf extension it does save to that detination.  But...when I try to open that .pdf file I receive this messege:

"There was an error opening this document. The root object is missing or invalid."

How do I correct this issue please?

As Jeff has asked, what error mesage do you receive when you try and open any pdf files in finder?

It may be the linkage to the default program has changed.

Use this url to check on the default link, and change it to Preview or Acrobat Pro or Adobe Reader.

Hi

I don't know what the problem is but Safari seems to work better but I still

can't open PDF. Sometimes I can download them and save them on my desktop

and then open them but all of a sudden I am not sure what happened but I

can't opened Adobe. And I haven't gotten any help from anyone. If I do I

will let you know. Thank you for responding.

See my posting on the forum (above).  We had the same thing, and now my brother has the problem.  Ours happened in Firefox, but it's worth trying as well for Safari, as the problem is in the Internet Library file on the hard drive.  Do this:

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.

couldnt find adobe plugins to delete.  used spotlight.   -----  i installed and unistalled acrobat reader for mac on leopard 10.5.8.  using safari as the web browser.  tried to open a pdf on safari.  nothing happened.  got a message that "adobepdfviewer.plugin" (this may not be the exact text that is why it is in quotes).  followed opquilt direction on how to restore safari/web browser to open pdfs again.  there was nothing in the library/internet plugins for me to delete.  went to spotlight and typed in "adobepdf" this showed me 2 adobe plugin files (exactly where opquilt said they were!! why i didnt see them when i used Finder to go there i dont know... wasnot logged in as administrator, perhaps).  i selected them and deleted them in spotlight.  had to enter the administrator user name and password before they were deleted.  now it works just opquilt said it would.
