I dont know what is Adobe plugin. I will investigate. However, just based on its name, I would probably recommend removing it. The combination of these two words, ``Adobe'' and ``plugin'', makes me feeling uneasy :) Which brings us to the second point: there is no good open-source PDF viewer. If you care about using open source, then go HTML.

Yeah, I don't have the Adobe PDF plugin either. But Firefox and Chrome use PDF.js which is open source AFAIK, and works with page references.
