Attention Scratch Xi Users

Scratch 2.0 Goes From HTTP to HTTPS Preventing the Xi Server From Connecting to the Scratch Xi Client

This change prevents Xi from making a websocket connection between the Xi server and the Xi extension client loaded into Scratch.

Snap! is unaffected and will continue to work as normal.

We are working on providing a solution using secure websockets, but in the meantime, there is a workaround for both Chrome and Firefox by setting a flag in the browser.

For Firefox, enter this "url" into the browser:


When the warning screen appears, click on the "I'll be careful I promise" button.

Next, search for network.websocket.allowinsecureFromHTTPS and click on the line to set it to true. Then close and reopen Firefox.

For Chrome, enter this "url" into the browser:


and then search for Allow insecure WebSocket from https origin.

Then click on "enable". Close and reopen Chrome.
