I am using an old PC as my 'good one' has a heat sink about to crap out
Here are the specs:
http://shrinkurl.org/backup/
Actually has 184 mb ram
I am needing a browser:
needs to be FREE /small/lightweight
Not use a bunch of resources / CPU's working
allows auto fill on yahoo mail....more?
NOT use

IE to function!
NOT have the typical 2 inch header found on most of above listed IE especially!
I've tried:
FireFox
Opera - can't TELL you how many tracking cookies flock to this browser!
Avant/Dimension/Zabidoo/Tablane/Phaseout/Maxthon/Slepnir/GreenBrowser/K-Meleon/Browse 3D/FF2.0.0.9
Attempted to install Zudul but it took too long to install so canceled it.
Thank GAWD for CCleaner....
Am currently using Chrome - however - no auto fill on yahoo mail and Each 'tab/window' uses CPU's besides one extra for USER -
( only one person on this pc - me, )
also no screen preview on tabs open without adding a plug-in
Has stalled several times netting me the SNAP! page
I LIKE the way the 'folder look or tabs' Chrome uses - hate the typical IE 2 inch header
thought I would toss this out here to see if anyone has an idea...
I KNOW I need more ram, and am working on it!
Thanks in advance!
