This is my first optimized build of firefox. 

1. Download the firefox tarball (https://developer.mozilla.org/en/Build_Documentation)

2. untar

3. copy the configuration to the file .mozconfig

4. $ make -f config.mk build

5. $ cd dist

6. $ make package

7. cp firefox-3.0.4.tar.bz2 to the target and untar

I must say that the optimized build is really faster than the standard build. I have a Notebook with a 1.6Ghz Pentium M and now it is feeling like a Desktop-System, or so. I have attached my build, it should run on every Linux. If not do not hesitate and contact me.
