If 2+3 work you may want to try removing/renaming any extensions.ini file 
in the profile, which will cause ffox to rebuild it on next startup...

There is a known bug in firefox 3.6 which causes the wrong data to be put 
into extensions.ini if any component of the path to the profile is a 
symlink, which then causes firefox to crash on next startup - if you have 
any extensions using certain features.

A fix has been committed to the ffox 3.6 tree but I don't think it is in 
any of the released versions yet...

Currently we have a workround wrapper which removes extensions.ini on 
ffox startup, and seems to have cured it for our users - at a small 
startup cost.
