With my system specs, I am trying to go as lightweight as possible.

I've chosen K-Meleon 76.4.4 Goanna and Sumatra PDF 3.3.3-64.

KmeleonBrowser.org's FAQ, Forum's, and Tutorial's make me feel like I am the stupidest person on the face of the planet.

I'm used to Google Chrome which has the pdf viewer option through Adobe Reader.
Google Chrome and Adobe Reader are both very heavyweight.

How can I view pdf pages in K-Meleon Browser before downloading the pdf file?
