[Camino] Problems with PDF browser plug-in installation working

Hi - 

I'm new to Camino (installed today) but very interested in using it,
*especially* if it can view pdf files inline, which is the only reason I use
Safari over Firefox on my Intel Mac.

I've downloaded the Shubert|it PDF Browser Plug-in v2.2.3. I've installed it
(while Camino was closed) in myhomefolder/Library/Internet Plugins folder.
Camino still downloads pdfs. Then I tried installing it in the root
Library/Internet Plugins folder (while Camino was closed) - still, pdf files
download rather than open in the browser.

I haven't found any Camino preferences to specify how to deal with pdfs.
While PDFBrowser is a supported plugin for Camino, none of the Camino or
PDFBrowser documentation addresses this problem.

I'm not sure what to do at this point, but I don't want to give up on Camino
til I've tried all the options.

Thanks for any help,

Aliza
