Adobe Reader Plugin not working in Snow Leopard

[washer]

I recently upgraded my HD and did a clean install of Snow Leopard. Before the upgrade, I could view PDFs in both Safari and Firefox in-browser with Adobe Reader. I prefer this to Preview because of the toolbar options.

After the upgrade, even though I have Adobe Acrobat Pro and Adobe Reader installed, I can not view PDFs in-browser with it. Safari defaults to Preview as a reader and Firefox defaults to download the PDF (I thought it would install the plugin when I installed the Reader. I can not find an independent reader plugin for firefox online).

I am running Safari 4.0.4, Firefox 3.5.5, Adobe Reader 9.2.0, and Adobe Acrobat Pro 8.1.3.

Any help?

Have you tried opening up Reader and selecting "Repair Adobe Reader Installation" from the Help menu? That will normally check for a missing plugin and replace it if necessary. Note that with the same software here at work, Reader 9's plugin is newer than Acrobat 8's, so it will take precedence.

If you've already done that and it still doesn't work, I'd recommend completely deleting the App(s) and plugin, and reinstalling from a fresh download, just to rule things out--that usually fixes Adobe problems for me.
