Hey @evhan55, don't know where you are on this, but I just noticed that it's not even necessary to have a connection. Just having a BLE-enabled extension loaded and search for a device makes the browser crash when refreshed.

@knandersen Cool, thanks! I haven't looked more into it yet but this is good to know!

Testing this today, discovered:
- Setting
window.onbeforeunload = this.disconnect;in the Microbit extension prevents Scratch Link from crashing on a page refresh, essentially fixing the issue. However, @cwillisf believes it's probably best to fix this in Scratch Link itself instead of on the client side window.addEventListener('beforeunload', this.disconnect);also fixes the issue, and is safer if it doesn't overridewindow.onbeforeunloadglobally
