Am no expert, and not sure why saving a webpage 2x per day would be so tedious?
But since you have already blocked images and flash, try blocking some more stuff. Especially blocking css seems to free a lot of RAM, at least on my ancient machine.
Have recently posted some macros for bandwith+RAM+Privacy savings, perhaps want to try. Start with "priv3buttons", it's the easiest for testing, with quick toolbar buttons.

There sure are countless other possibilities too, considering the 1000 Mozilla prefs ;-)
KM75.1 now has a "settimer" command in macrolanguage. Perhaps it can help to save a page in regular time intervals, and to minimize/maximize a window (they say minimizing it would free RAM). And it could open new pages... e.g. save the current page/ close it/ open it again in new window - if that would help anything?
I really don't understand the problem well enough, technically, and on my old main machine with 256MB RAM cannot test myself, so these suggestions are rather theoretical thoughts ;-)
But other people here know a lot more about such stuff, while I only have more experience with (simple) macros.
