  config.trim_on_minimize??
  
  There is no such field in my firefox, in the about:config page. I'm using firefox 3.1. Is it working for anyone??

  Scorpion right click there and then add new entry of boolean type and set its value to true. If it is not working try making a user.js file(add entry to it) in pref folder of firefox. I tried but it was showing access denied to me.
  
  PS: I will try more and will get back to you but you also try if it works and let us know. 😀

  Wow man, its magic 😁
  
  Add following entry in all.js file in greprefs folder of firefox3 version and save it.
  

  pref("config.trim_on_minimize", true);

  When I minimize the window. it is giving quite a bigger amount reduction in RAM consumption.
  
  See just now my Task manager is showing 28,596K against firefox.exe
  and when i minimized it, it showed around 3452k. Though it will keep on varying.
  
  I must say a very good information told.😁

  But I have a question regarding this- if anyone of you know the reason Please tell 😀
  
  When I made the same changes in my laptop - firefox 3 it didn't allow me to modify all.js file(saying "Access is denied") but just now I tried it in my office system (same version), it is working 😕 How?
  
  Is the directory path matters?
  
  Any ideas anyone?

  Access denied? Maybe you've your firefox running? Do you get the same error when you try to edit the file when FF is closed?

  Here's more information: Config.trim on minimize - MozillaZine Knowledge Base
  
  It says that you should leave it to 'false' to maintain application responsiveness. Anyone's seen delayed response time when the setting is 'true' and FF is maximized (from the tray)?

  Man, My firefox was already closed while changing the file. See the error message which I am still getting. I gues it may be beacuse of location? Has anyone tried to the change file in following location? 😔

  Well everything I do on my system is in Admin mode for me. I don't know which Admin mode you are talking about. Just now I tried installing firefox again in C:\ location instead of C:\Program Files , now it allowed me to change that file though I could not see magic of this statement anymore 😔
  
  Following is the link that you are talking about and have posted almost a year back(not months back 😉) 😀

  I have been playing with this today. FF is open, and Task Manager running and set to "on top". Processes list shows FF is using 130k mem, 251 VM. Minimize FF, mem drops to 18k, VM is same. Over the next minute or two, not touching the computer, mem slowly creeps up to 118k, VM is same.
  
  It seems like the setting must clear out work space memory, and then immediately starts to fill it again as FF does it's thing. I guess this setting isn't much of a help.
