And I can’t comment over on SO because I don’t have enough reputation there. Awkward. Well, please relay this: Discourse is very nice, but the only login system they have unfortunately is Mozilla’s dying Persona system. I had the exactly same trouble until I turned off all my ad blockers—for some reason the login system didn’t list Persona, and I just had to allow everything globally. Once I got the cookie I was able to turn things back on, though.
I believe that tracing out the internal [quote=“kousu, post:9, topic:7085”]
return window.openDialog(getBrowserURL(), “_blank”, options, aTab);
[/quote]
will tell us how to setWindow() as well.
