You made me curious about memory use.
FF is my main browser and has been since 2002.
Right now, my computer is at 11 days of uptime and Firefox has been open that entire time. I'm at 12 open tabs, albeit none are particular intensive.
I've noticed that after extended Firefox uptime(30 days or so) things can start not working right, but overall so far so good.
In any case, here's a snapshot of my current memory use
