Mac Forum / Applications / Firefox / Mozilla / September 2005

I believe that the Mac version of Seamonkey will allow you to specify
which hard Drive/folder you want it to store the profile in. It has been
a long time since I launched the profile manager. With the Mozilla suite
when you launched the profile manager to create a new profile there was
an option to specify where you wanted the profile stored. I believe that
if you specified a different location for the SeaMonkey profile than the
Mozilla profile than each program would use its own profile.

Take care with this tip since I haven't tested it out. My best guess is
that creating a new profile in a different location will cause each
program to use its own profile I am not 100% sure. By creating a new
profile with SeaMonkey you may confuse Mozilla and it might want to use
the new SeaMonkey profile instead of the old Mozilla profile.  This is
unlikely. If it does happen it is easy to fix. To fix it go to your home
folder and navigate to the Library folder and then to the folder titled
Mozilla. In the folder titled Mozilla you will see a folder called
Profile. Move the contents of this folder into the folder titled Profile
that you created with SeaMonkey and things will work again.

In either case my tip is safe to try, BUT for safety Make a duplicate
copy of the Mozilla folder in the folder Library (this backs up your
Mozilla profile) just in case something goes wrong and you lose your
profile. It is better to be safe than sorry.
