Dominick Grift:
its x86_64 vs. 686 issue
x86_64 does not need execmem.
But both of these systems are x86_64 systems.
More exactly, why doesn't x86_64 need execmem? Firefox does
apparently allocate memory that is both executable and writeable on
x86_64 systems too.
you can also set boolean allow_execmem to true i believe
Yes, that makes firefox runnable again. But if possible I would
prefer to have it turned off. And it does work with it turned off on
the fresh install, so I guess there is some way to do it.
