9gb for 4 tabs of HN sounds ridiculously wrong. (Thanks for mentioning what is in your N tabs. I tend to ignore complaints that only give the value of N. Nobody would say "Why is my computer running out of memory when I'm only running 20 applications?") Can you please file a bug at https://bugzilla.mozilla.org https://bugzilla.mozilla.org and include an about:memory dump? You'll probably need to report what addons you have too.
