Adobe has a knowledgebase article on this.


http://kb2.adobe.com/cps/905/cpsid_90508.html

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:


User uploaded file

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.

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.

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.

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;
