I just shut it down every few days and start all over again.
I shut it down twice a day... also never run more than two tabs at a time... perhaps I'm not straining it enough? Have to admit that my bite on the web is perhaps smaller than others as I've never run into fail or paging as others have noted.
Quick poll: How many tabs open to do you maintain, or cause to be opened when starting Firefox?
