Well, the latest version of Chrome came out a little earlier than I thought it would, breaking XKit.
I am still trying to set up the HTTPS servers that would prevent Chrome from blocking XKit, which should be available in a day or two, hopefully, but in the meanwhile, if XKit stops working after updating Chrome, click on the shield on top-right and click “Load unsafe script” to make it work again.
I’m terribly sorry about this. I’ll let you know as soon as an update is ready. Thank you for your patience and support.
