PDF links, downloaded instead of opened

Hi...

When I click on a PDF link on a webpage I get prompted to either open in Preview (default) or save to disk. But even when I choose open in Preview the PDF is still downloaded first.

How can I change that?

Firefox 2.0.0.3.

You need either

1. The PDF plugin
2. Adobe Reader (like the PDF plugin, only slower and buggier)
3. Safari

I didn't know Reader was buggy.

Download it and it will install the plugin for Safari automatically.
