I am having trouble opening PDFs in Safari. Whenever there is a PDF embedded in a page, I get an empty space with "missing plug-in" displayed. I have done some searching and it seems the problem is related to Adobe Reader 10 and Safari 5.1 I have AR installed (I need it for PDF forms and documents containing greek letters that sometimes don't display properly in Preview) however I very rarely use it and I keep Preview as my default app for PDFs because the interface is much better. I have never used the AR Safari Plugin I unchecked it at installation so it has never been on my computer, however some aspect of the installation has screwed up the way Safari handles PDFs. If I could get it to work by uninstalling AR that would be a reasonable compromise and I would be happy to get by without AR. Unfortunately there is no proper uninstall tool (it installs using a pkg file) and moving it to the trash and emptying it then restarting doesn't help. Basically, even after removing it, AR has crippled my computer. Short of reinstalling Lion (although I fear time machine might even bring the problem back), is there anything I can do to restore the way Safari works with PDFs? Is it possible to reinstall Preview and Safari, and might that even help? I need to access these documents for my masters research project, and to me a workaround such as using a different browser or PDF program isn't really a solution. Any suggestions would be greatly appreciated. Thanks!
