38.0.5 is safe. I learned it myself when trying to use internal service.
Secure Connection Failed
An error occurred during a connection to 10.xx.yy.xx. SSL received a weak ephemeral Diffie-Hellman key in Server Key Exchange handshake message. (Error code: ssl_error_weak_server_ephemeral_dh_key)

I wish they gave option to bypass it.I'm running 38.0.5, the weakdh page says I'm vulnerable

It's hard to tell from the paper, because they don't include either specific build version numbers of browsers / servers nor date of publication, so their results are difficult (e.g., impossible) to reproduce exactly.
Interesting, weakdh says I'm safe...
Both on Mac and OpenSuSE.
https://bugzilla.mozilla.org/show_bug.cgi?id=1166031 and https://bugzilla.mozilla.org/show_bug.cgi?id=1138554 say explicitly wontfix for 38.0.5
Maybe you manually fixed it some time ago and don't remember?
