I'm not an expert on Firefox memory usage, but just at a glance, I wouldn't expect it to be; 700MB is well within the limit of how much memory can be addressed in a 32-bit process. There _are_ cases which can lead to needing the extra per-process memory, however, even without advanced in-browser games or 3D CAD apps or the like. For example, on my personal home computer, Firefox is currently taking up roughly 5.6GB of RAM; this is because there are over 4,000 open tabs, all ordinary Web pages, although only maybe a hundred of them are loaded. (Quite a few more - possibly several hundred - have been loaded, then closed, since the last time the browser was launched.) The highest memory usage I remember ever seeing from Firefox is close to 8GB. This is not a _common_ use case, but it does exist; one of my brothers is more in the vicinity of 1,000 tabs and is on a 32-bit Firefox build, and last I heard, he had largely migrated his day-to-day browsing to Chrome because all those open tabs mean he doesn't have room to do very much in Firefox without it being killed for hitting memory limits. -- The Wanderer The reasonable man adapts himself to the world; the unreasonable one persists in trying to adapt the world to himself.
