Reduce Firefox memory usage

Optimize Firefox memory
Firefox memory usage too high

In this chapter
I will simply teach how to reduce your Firefox memory usage.
Usually my Firefox can reach from 100k-300k memory usage. But with this, about 60-90k

Case
Im using Firefox 3.6
Window XP Home Edition SP 3
This tutorial is actually come from aviransplace

The Setting
But here my settings. You can custom it as you want.
Refer to the aviransplace to know what is the value should be put
1. At the address bar, type "about:config" and press enter
2. browser.cache.disk.capacity = 4096
3. browser.cache.offline.capacity = 4096
4. browser.sessionhistory.max_total_viewers = 2


Note
When using Firebug for developing website. I realize that the more error Firebug detect, the higher my memory consumption (and it does not go down).
To view current memory chache usage type "about:cache?device=memory" at addressbar

Additional settings.
Take a note that Firefox plug-in also can affect you memory usage.
You can check it ad Tools > Add-ons
In my case I only leave
Firebug 1.5.0
Flashblock 1.5.11.2
LogMeIn 1.0.0.496

Once done. My 1 tab with google page consume me 70k memory usage

Another additional setting
In case you want a ad hock browsing. It is best for you to keep a FF with a safemode start.
Simply duplicate the Shortcut of the FF
At the new Icon Right click > Properties
And add new words "-safe-mode"
It become like this

"C:\Program Files\Mozilla Firefox\firefox.exe" -safe-mode

Guess what. Its 55k memory usage

Now Im using Google Chrome (most of the time) because of FF will run 1 .exe file just for flash. I didnt remember the name but it was on the task manager. This result a very high CPU consumption in my PC. I heard it was because of latest FF and this is still on a testing phase.

I think these method is already obsolete and cannot be use anymore
