Sorry to dredge up a REALLY old thread, but someone last year from the Camino team private-messaged me and offered up a custom build of Camino that respected the header-footer preferences in the *prefs.js file.
That worked great, and I was hoping that whoever that was could PM me again, as we would really like the same hack done to a newer build (one of the recent nightlies, or something).
Thanks!
(Unless anyone knows of a way with recent versions to disable header/footers without resorting to hacks - I couldn't find any exposed UI for it, and regular builds ignore all settings in the pref files referencing header/footer printing.)
