It sounds like it was a nightmare. I wonder why Firefox is so finicky?
RT @DrScriptt@twitter.com That was a trip. I couldn't save a picture that Firefox had downloaded using the usual methods.

I had to disable HTTP2 (https://techdows.com/2014/02/enable-http2-in-firefox.html) and save the ephemeral SSL keys to be able to decode a packet capture.

But I got the file! 😈
