UPDATE 2019/09/26:
THIS VERSION IS BROKEN! The "whitelist all URLs" and "blacklist local address" are not working, so "use enabled proxy by patterns & order" doesn't work.

Very good proxy add-on, but not so powerful as the old version. I really need the customizing click action feature so that I can customize one-click switch on/off function. In this new version I have to click twice to switch on/off.
