It looks like I'm in the good(or at least popular) side of the forces :)

I use both VMware and Wine, because there's no way to run Visual Studio 2005 in Wine :(

This example will involve moving a profile from Windows XP to Ubuntu 7.04, but the basic idea can be used to move profiles around in many other scenarios.

Step 1: Find Your Files

In Windows XP, look in:
Firefox: C:\Documents and Settings\<username>\Application Data\Mozilla\Firefox\Profiles
Thunderbird: C:\Documents and Settings\<username>\Application Data\Thunderbird\Profiles

You should find a sufficiently cryptic folder (e.g. “b455b37.default”). You can check inside to see if it has the data you want (ie. bookmarks.html for Firefox, a Mail subfolder for Thunderbird, etc.). That’s your profile folder, the one you’ll need to copy in step two.
