Subject: profiles & preferences file on various platforms

Following are the locations of the preferences files on various platforms.

Of the 3 platforms mentioned below, what actually changed is Linux.

Windows and Mac remained the same.

    for profile 'default' : ~/.mozilla/Default
    for user created <profile name> : ~/.mozilla/<profile name>

    The root directory for profile info storage used to be ~/.mozilla/Users50/ and is now changed to ~/.mozilla as shown
    above.

Mac :

    for profile 'default' : :Documents:Mozilla:Users50:Default
    for user created <profile name> : :Documents:Mozilla:Users50:<profile name>

Windows :

    for profile 'default' : <3 levels up from the exe location>\Users50\Default
    for user created <profile name> : <3 levels up from the exe location>\Users50\<profile name>
 

In any case the most important thing is make sure you delete mozregistry.dat on windows ( c:\winnt or c:\windows or equivalent), Mozilla Registry on Mac (System Folder:Preferences), registry on Linux (~/.mozilla/) before you install/build and run the new executable. It might cause inconsistencies otherwise.
