Thanks Stephan, I'll test your patches.
And I bet that the same will have to be done for Firefox ESR 21?
BTW, I don't understand how upstream code is versioned. Shouldn't your
original patches have been ported to the new JS engine by upstream
when they released > Firefox ESR 10 versions?
Otherwise, what would prevent such breakages in the future with ESR 28, 35, ...?
And the same for Webkit? I've reoppened bug 642750, as Epiphany status
is as bad as Iceweasel ESR 17 since they switched from Webkit 1.8.1 to
2.0.4.
