Make Firefox Work Faster

Another Speed Up Firefox post ???
Naah!!
actually for any given software, the moment you manage to master it, a new version appears. and your system remain the same. i saw one anonymous comment at Boost speed of firefox
That He/She is using older system firefox2.0.0.2 Was working great on his/her system But firefox developers don't sit silent they keep upgrading Firefox. as i upgrade my Firefox Version to 2.0.0.3
i was unable to work efficiently, may due to my lower configuration Any solution???

Here goes yours :
1. Enter the Configuration panel of firefox by about:config in address-bar .
2. Search and Set
browser.cache.disk.capacity to 3/4 th of existing value.
3.Search and set
browser.cache.memory.capacity to 3/4 th of existing value.
4. Restart you firefox. and you will have enough speed from your system to play with firefox.

Explanation :
Actually browser.cache.memory.capacity and browser.cache.Disk.capacity are the parameters that specify number of memory should be given to the Firefox While Execution. So setting it to lower value reduces load on the RAM and you work faster with your lovely Browser.
