FireFox 1.5 is in Beta 1 testing phase!
http://www.mozilla.org/products/firefox/
Loaded 1.0.7. Fires on all cylinders.

Loaded Firefox 1.5 Beta to a separate folder under advanced install. It
takes over the desktop shortcut first use, but 1.0.7 still runs directly
from the programs folder. Reverted back after first use to 1.0.7

I lik'em enough to run Beta testing, pick your poison.
Placed link to the 1.5 folder and both running fine.
