Firefox is a server application

Have you ever seen a program that took 700++ MB of your RAM?

Now you can boast that you’ve seen one.

Lucky I have  2 GB of RAM

The version of Firefox that I’m using is  from http://jaist.dl.sourceforge.net/sourceforge/portableapps/Firefox_Portable_2.0.0.12_en-us.paf.exe

And this are the extensions and themes installed
