In before Opera.

Anyhoo, to answer your question:

But I still find Firefox sluggish even after doing all this stuff.  Must be a "feature".  LOL

The 1.0 and 2.0 series are broken, just don't use them.  Use Firefox 3.0 and enjoy the low memory usage.

OP here. I do like Opera better, but I  do need to use firefox here.

Tried those tips on mozilla zine, didn't work.

SCORE!!
I was using opera-usb before I jumped to firefox portable because I was having some problems with opera.
Now I found out a way better portable version of Opera at www.kejut.com/operaportable and am currently using it.
Farewell firefox!
If any of you know of a better yet portable version of opera, post it. KTHXBYE
