Fix Your Desktop

I just upgraded to Firefox 3.0 on my Mac OS X system, along with millions of other people apparently, and just realized that one feature I've lost is the ability to view PDF files within the Web browser. I don't want to launch Preview or Adobe Reader, I want to view PDF documents I encounter within Firefox. Is there a solution?

• How do I make Firefox 3 my default Web browser?
• 10.5: View PDFs inline in Firefox 3
• Make Adobe CS apps run on case-sensitive volumes
• 10.5: Quick Look files in Open and Save dialogs
• Edit PDF in OS X with Skim
