I'm with Bill and John. I've found Adobe's Acrobat Reader to be bloatware of the worst sort, and would advise anyone who asked to uninstall it and install Foxit Reader instead. I would not
use the two together. Foxit v3 is a major improvement over v2, and opens even large PDF files on the hard drive within just a few seconds.
For PDF files on the web, I recommend the PDF Download
extension, which gives one several options including opening the file, downloading it, or viewing it as HTML.
