Browser.proxy.register documentation

Hi. Where I can get some sort of documentation for new browser.proxy.register and browser.proxy.unregister in FF57?

Keywords: dev-doc-needed in https://bugzilla.mozilla.org/show_bug.cgi?id=1371879.

You can do it yourself if you willing, see https://developer.mozilla.org/en-US/docs/MDN/Feedback.

register is already documented here. But unregister is missing.

Can I use string return in PAC script in FF57? Will string return be deprecated in future?

Also why PAC script is not working in FF 57a right now? It’s part of working process for alpha version?
