As Rob described in Bug 1645204 , our handling of bypassCORSChecks leaves a huge vulnerably open for our users. Regressed by bug 1450965. Fortunately this was in 69, so ESR68 is not affected. As the next ESR release is so close, I would like to backout the changes made in bug 1450965.
We will still work on the fixing the original Bug in 1645204 asap.

i would like to remove the risk of shipping the vuln, since the original bug we tried to fix had only a small impact on users. Since the regressing patch did not land on ESR, backouting it would pose no negative effect for our esr users.

Since ESR78 has already shipped with the feature from bug 1450965, we shouldn't just back out the patch.

For that reason, I suggest to move the patch back to bug 1645204. That bug already has a real fix, so the patch here is just removal of unused code. There is not really a need for two separate bugs.

@sstreich, could you move this patch back to bug 1450965, and mark this bug as a duplicate of it?
