we should ensure that we disable this for quantum or figure out how to add an exception to the proxy.

How did this change? I was disabling it for the quantum-pageload test.

I probably re-enabled it for all talos- lets figure out how to disable it for quantum specifically: https://dxr.mozilla.org/mozilla-central/source/testing/talos/talos/ffsetup.py?q=path%3Affsetup.py&redirect_type=single#72 that makes sense as to why this was not set!

Hmmm yeah it's being set here in ttest, just for quantum-pageload but it must be overwritten somewhere else: http://searchfox.org/mozilla-central/source/testing/talos/talos/ttest.py#110

possibly this is during the profile warmup where the problem is, that is where I added the env var in order to try to fix the webext stuff, despite marionette not working.

Interesting, I can't reproduce this. I pulled the latest central onto my local Win 10 test box, did a build, and the talos quantum-pageload-e10s tests ran fine (mach talos-test --suite quantum-pageload-e10s). All the mitmproxy pages are loaded (and results reported).

Oh wait I just noticed you use -a to run each test separate, ok right. Did you add the --mitmproxy argument on the command line also?

i.e. this works on my Win10 box: mach talos-test -a quantum_pageload_google --mitmproxy mitmproxy-recording-google.mp

where would you get mitmproxy-recording-google.mp ?

The file itself will be downloaded automatically (inside the playback archive). This same command line is automatically set in in the talos.json talos_optios for the quantum-pageload-e10s test. Maybe I should add code to have talos grab that if someone tries to run one of the quantum_pageload_* tests just via -a and not expect it on the command line.

+1 for that
