setting SSLKEYLOGFILE (for HTTPS decryption) does not work

[Victor Sudakov]

Dear Colleagues,

I have noticed that "env SSLKEYLOGFILE=/var/tmp/keylog.txt firefox"
does not create keylog.txt on FreeBSD.

On Windows, this environment variable works as expected (creates a dump
file with SSL keys to be fed to Wireshark for HTTPS decryption).

What am I doing wrong? I've tried this on FreeBSD 11.2 with FireFox 62.0
from the FreeBSD default package repository.

This is a rather standard recipe, it's odd that it does not work on
FreeBSD. Any help is appreciated.
