I came across this tip whilst looking for an explanation to my high Firefox memory usage, but cannot get my head around the 'Explanations' bit. Maybe I am a little thick, but what exactly does it mean...............'Averagely we surf less than 5 of the websites we previously surfed before'.

------------------------------------------------

How to reduce memory usage in Mozilla Firefox

1. Type about:config in the Firefox address bar
2. Search for browser.sessionhistory.max_entries
3. Double click on the value 50, change it to something lower, 5 should be good.

Explanations

Averagely we surf less than 5 of the websites we previously surfed before, there is no need to usage up that much memory (which is 50 by default)

[dvk01]

Firefox loads the list of previously visited sites in that session to its memory ( by default that is up to 50 sites) it is very rare that we revisit more than 5 or so sites in the same sesion, so need need to use large amounts of memory with redundant information
