I love Chrome and when Chrome Portable came out, I started using it instead of Firefox on my thumb drive for my personal account. But since the new system allows only one Google account open at a time, and since our firm has recently moved to a GoogleApps business account (which is great, BTW), I can no longer have BOTH my business account and my personal account open simultaneously. So I've had to re-install Firefox Portable on my thumb drive for use with my personal Gmail account.
