I think Mario is talking about the runtime memory usage. I mean, disk space is cheap these days...
It's possible to tweak Firefox to stop caching pages, multi-pipeline downloads etc. and there's this nifty addition to the config that has Firefox strip down to sometimes < 10MB of memory usage when minimized. If you have a decent amount of runtime memory for Firefox saaay 30+ MB this could be the way to go.
Wow, I didn't know it has a built-in XHTML debugger, download accelerator, music player, FTP client, GMail virtual drive client, HTTP header viewer, world map plotter... Opera must be waay more bloated than I thought!It's because Opera has so many more features to begin with
You could try hack the Firefox source to make it cache stuff to disk or something, heh. Or refuse to cache certain stuff at all. It will probably save 80% on memory usage... and increase CPU/bandwidth usage by 5+X Well it's your choice. Can't you upgrade the RAM chip or something? Granted, notebook stuff ain't cheap, but this would seem to me a worthy investment if you're intent on extending the useful life of your computer as long as you can.
