Why wasn't it open source to begin with? At last then if they had lost interest in it, it could have been worked on by others all this time. Not to mention, doesn't the MPL require that? I'm not sure, since I haven't really dealt a lot with it.
What would be nice is if it could be 'leanified' enough to run on a 68k machine, but I suppose we have netsurf for that. Firefox is a bit on the fat side for it.
