In Safari, I use two finger dragging with my trackpad (on a MacBook) to scroll through websites. I've noticed that whenever I try viewing a PDF document, (i.e. the URL in the address bar ends with .pdf) the scrolling sensitivity is very different than the normal Safari scrolling sensitivity. It scrolls way too fast (i.e. it's too sensitive).

My guess is that it's a problem with the Adobe Reader plugin which doesn't implement scrolling using the same algorithm as Safari's. Is there any way to fix this? What about using a different plugin for PDF documents besides Adobe Reader?

Safari can open PDFs using Preview without the need for Adobe Reader to be installed. In my experience, Preview in Safari is faster and smoother than Adobe's Reader plug-in.

See this question for how to disable the Adobe plug-in.
