How do you install Firefox or Opera in such a way that the installed version is completely independent of other installs of the same browser.

This is Windows specific. I'd like to use my own installer to install a browser which will be run in "chromeless" mode to allow the user to access a web-app.

I want the installed browser to not be disturbed by other installations of the same browser whether they come along later or sooner.

Can someone point me at directions/examples for this ?

I've seen Launching Firefox into “chromeless” mode from command prompt but it doesn't address the issue of installation independence.

EDIT: Having seen Brad Pattons reply I realised I missed something out of this question. I want the browser in question to have auto-updates turned on so that it recieves security patches etc. For this reason I don't think a 'portable app' approach is useful (unless there's something about those I don't know ?)

No need for third-party 'portable' installers for Opera. The standard Opera installer allows you to install a standalone installation:

Opera stand-alone installation

This should auto-update just like the regular installation.

Use the versions of those browsers meant to be run on a flash drive (aka the portable versions) but put them on the local drive. They are designed to be self-contained with hooks into the registry, etc.
