I am using a Dell Latitude d610 about 7 years old. When I click a link/bookmark the arrow in the top left hand of Firefox never seems to finish loading,
I have been having the same problem with FF for some time now, but I just click the red X to stop the cycling, then immediately click the recycle and the page usually loads pretty quickly.

IN EDIT: Obviously something is hanging up the loading of my pages in FF, but don't know what, and this cancel and reload seems to work.
