I lost my ability to view PDFs with update and Lion install. Says "plugin missing", please help?!?!

Are you using Safari, Chrome or Firefox?

Adobe has a knowledgebase article on this.

Acrobat family

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 2011. 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.

Recommendation to Customers/Users:

For Acrobat customers who utilize functionality like forms, digital signatures, portfolios, guides, 3D, extended PDFs and rights management, and who require the Acrobat plug-in to render PDF documents in the Safari browser, Adobe recommends that you continue to use Safari 5.0.x and Mac OS X 10.6. We will provide updates as we continue to investigate this issue.

Definitely looks like a bug.

Running 10.6.8 and the latest Safari released on 7/20/2011 Safari 5.1 (build 6534.506534.50)

Adobe Reader is NOT installed and when trying to embed a PDF with this code:

<object data="onlinesetupdiocument_new.pdf" width="100" height="100" >

won't display

</object>

<embed src="onlinesetupdiocument_new.pdf" width="100" height="100"/>

in Safari 5.1 (build 6534.506534.50) on 10.6.8, I get this:

In Google Chrome, it displays both of these as expected:

There are some PDF plug ins that will allow you to open pdf files in safari. I searched for "pdf plug ins safari" and i saw one called schubert.

I use electronic databases like CINHAL and pdf files open up inside safari, with the new os x lion update I kept getting missing plug in from adobe.

it seems easy to install and works decent.

i am having the same problem,ur method worked for me.but well, shouldnt safari is able to open pdf file by itself? why do we need plug-ins ? y cant we open the web. like we used to do in the previous mac os which by just simply click the link?

The schubert plug-in worked for me. Thanks!

I have the same problem aftur Lion upgrade, both in Safari and Firefox (and Opera).

But, Chrome works fine !

- One pays for th schubert plug-in.

It is a bug, and it's on Apple's radar. I've reported it at WebKit.

I sure hope that both Adobe and Apple fix this issue ASAP!

I am having the same problem with safari and Firefox....Chrome works OK....

There are actually two different issues with regard to PDF viewing in web browsers. On one side it's the incompatibility issue that Adobe has with the PDF Reader Plugin under OS X 10.7 Lion. On the other hand it's the Safari problem, where embedding PDF's with < OBJECT > and/or < EMBED > no longer works. The FireFox problem is related to the Adobe incompatibility issue.

Chrome has their own PDF viewer plugin, therefore that works.

Try chrome , it works

or download schubert-it plugin

Those arn't solutions, they're are work-arounds. Fact is that Apple has created a huge issue by removing the support for embedding PDF's by using the W3C standards OBJECT and EMBED. Why are they going the Microsoft way by not respecting the standards and remove support for something as important as this.

By the way, the Schubert-IT plugin is as unstable as nitro, under Lion at least.

ivschie , can you offer a solution?

Nope, Apple is the only one who can offer a solution, since they've decided to remove the support for embedding PDF's in Safari 5.1 through the EMBED and OBJECT tags. Or maybe Adobe, but they've yet to release a new PDF plugin that is supported by Safari 5.1. But with the speed Adobe releases fixes for their software, I wouldn't get my hopes up that they will come up with a working plugin any time soon.

Edit: There's a nice article on the Adobe part on ZDNet;
