profiles.ini has a requirement that the sections are named Profile#, with the numbers increasing sequentially. The default profile is referred to by number. This sort of sucks, because you have to rewrite the file every time you remove a profile. What if we made this change: 1) name each profile section with a uuid 2) refer to the default profile by its uuid I'm only filing this because it would make some profile munging on android easier, though I wonder if it's worth actually doing this bigger change instead of just writing code to do the finicky renaming.

This bug is filed in a bugzilla component related to pre-Firefox code which no longer exists. I believe it is no longer relevant and I am therefore closing it INCOMPLETE. If you believe that this bug is still valid and needs to be fixed, please reopen it and move it to the Toolkit:Startup and Profile System product/component.
