This is the Firefox 53 version of bug 1339789, please read the summary over there.

I suggest to upgrade Firefox 53 to NSS 3.29, which is a small patch on top of NSS 3.29, to restore binary compatibility.
setting ff51, ff52 to unaffected, because those are handled in bug 1339789

ff54 will be fixed with the next nightly merge on m-c
Depends on: 1334108
We found an additional issue with NSS 3.28, bug 1340103.
We're trying to get this resolved ASAP.

NSS 3.29.1 has been released.

Aurora try build with NSS 3.29.1:
Summary: Upgrade Firefox 53 to NSS 3.29.1 to fix a binary compatibility issue → Upgrade Firefox 53 to NSS 3.29.1 to fix binary compatibility issues
Attached file update-to-3.29.1.txt
The try builds look good to me.

I think it's safe to pick up these two correctness fixes, which have been released as 3.29.1

(Identical story as in bug 1339789 for beta ff 52.)
