The actual NPAPI plug-in (pdfplugin.plugin) works in Camino trunk (2.0a1pre) builds, too. Just rename the .xpi file to .zip, unzip it, and put the pdfplugin.plugin from the "plugins" folder in (~)/Library/Internet Plug-ins on your Mac.

Some keyboard shortcuts (arrow keys/pgUp/Dn/home/end for navigation) don't work, but scrolling works, as do zoom in/out. Selection of text and copy work, also. It's certainly usable

Note the plug-in is *not* compatible with Camino 1.6.x (presumably it uses the new plug-in models introduced in Gecko 1.9) and breaks the existing "auto-download" of pdfs in Camino 1.6.x on Intel Macs.

Thanks Uncle Asad. I was wondering how to do this (where to place the plugin - I'd figured out the unzipping). I hope you post this on the Camino forums!
