It is not clear how to duplicate the problem from what is given. Since it appears to be a linux problem, I'm reassigning to Ramero.

Im not sure how to reproduce this problem. I can load http://www.cis.ohio-state.edu/~gunn/ and navigate back and forth from it. Marking worksforme.

yeah, i'm marking this verified. pgunn, if you see this behavior again, please try again, and refer to our bug writing guidelines on http://www.mozilla.org/quality/bug-writing-guidelines.html
