Same issue with version 66.0.3359.26-2. And reverting back to 62.0.3202.89-1 makes chromium working with proxy again.
Am I the only one to have this issue? I'm wondering, but since this is 100% reproducible I doubt... Thanks, -- Pascal Obry / Magny Les Hameaux (78) The best way to travel is by means of imagination http://www.obry.net gpg --keyserver keys.gnupg.net --recv-key F949BD3B
