[ALUG] A Fedora/Firefox question

Another Fedora "being too clever" annoyance! When I start Firefox it insists on going to the page:- file:///usr/share/doc/HTML/index.html The 'Home Page' in Firefox preferences doesn't override this, I have it set to about:blank. What were they thinking of to hard code this somewhere in the startup scripts! Anyway, does anyone know how to turn it off? -- Chris Green
