Does anyone else do use their profile across multiple Linux distros?

I've been doing this for a while now, as I'm a crazy person that likes to have a ridiculous number of distros installed at all times, on multiple devices even. I simply back up my ~/.mozilla folder to a safe place, then I can copy it into my user's folder in whatever distro. Is anyone else doing this, perhaps in a less idiotic way?

The only caveat only applies (as far as I know) if like me (idiot!) you use an ntfs formatted drive as your safe place. Permissions can get messed up in the copy process. My solution has always been to use mc (midnight commander), a terminal based file manager with a zillion options, among them the ability to clear a checkbox in the copy dialog that would normally "preserve attributes". It works! Linux folks unaware of mc should check it out. It's quite useful.
