SSLKEYLOGFILE with Firefox

edit

Which instructions are you using?
Did you give a full path to the file and is the directory writable?

C:\Users\foo>set | findstr /I ssl
SSLKEYLOGFILE=C:\Users\foo\sslkeylog.txt

Ah. I was distracted by a Firefox ticket about turning this feature off, and was left confused as to whether it was still supposed to be working or not.

I took your reply as indication that it should work, so had (yet) another look at my batch file.

And discovered a typing error in the path name to the file, which I've fixed, and it now works.

Thanks.

(Note to self)
To check version on Windows requires pipe

C:\Users\foo>"c:\Program Files\Mozilla Firefox\firefox.exe" -v 
C:\Users\foo>"c:\Program Files\Mozilla Firefox\firefox.exe" -v | more
