Changing Firefox Cache location

Firefox cache keeps eating up my profile space. It's very annoying to see this:


So I searched and found a fix on Freeware Forum > Firefox Cache:

* Open Firefox
* In the location bar, type about:config and hit enter
* Right-click in the white-space, and choose New->String. Enter the name browser.cache.disk.parent_directory and click ok.
* In the next box, enter the full patch to the directory you want to store your cache in. I used E:\Program Files\Mozilla Firefox\
* Close Firefox.
* Delete your old cache directories in
C:\Documents and Settings\%username\Application Data\Mozilla\Firefox\Profiles\%randomNum.default\
* Restart Firefox. It will create the directory specified above, if it doesn't already exist.

This same technique can be used to move your cache to a larger or faster disk."

That's not it, the history.dat is huge as well. So I searched again and found out a way to move the whole profile. Well, not actually moving but create a new one at a new location and copy the old data over.

First close all FireFox browser windows. Then go Start>Run and type in the following (or the path to where you have FireFox installed).
"C:\Program Files\Mozilla Firefox\firefox.exe" -P
This will let you create a new Profile without destroying the old one.

It works generally, except for some extensions like googlebar, it can't find some elements. I'll worry about that later...
