The control panel will not unistall version 3.6.12. After downloading version 6.0, and running setup, I have a dialogue box that says I must reboot computer to complete previous uninstalling of firefox. After doing this about 5 times, I still get the same message. Is there are way of bypassing this requirement so that I can install version 6.0? or how do I delete all 3.6 registry files and not lose my passwords and history of firefox?

I will try this, but I didnot get to that stage of asking to install to another folder. The wizard asks to reboot before it goes through these sub routines. Chris
