Hi @jscher2000
After a week of frustration I stumbled across your post.
I run ESR 52 on Mac/OSX.
I am not a developer and nothing on the bugzilla page/link you posted makes any sense to me whatsoever, so that’s not going to help me, sadly.
I downloaded the crt file at the other link in your following post, and imported it. (Even did it twice, to confirm - second time - that it was already installed.) Rebooted FF but no change.
Any idea where this is? (Hopefully with some instructions!) I cannot find any reference to it or relevant announcement by Mozilla.
Thanks in advance for any pointers you (or anyone else) can provide.
ETA just noticed you posted 2 hours ago - my bad, I first read it as 2 days ago, so is it still in QA? If so, where will I find any announcement once it is out of QA? The announcements at
