@tasket @firefoxwebdevs How exactly is it a security nightmare when it needs explicit user consent?

How much will these prompts proliferate?

@firefoxwebdevs This is really cool and I've been waiting for this feature for so long. I'm excited to use it but I still don't understand how. The permission is required but what triggers the popup to grant the permission?

@hisold @firefoxwebdevs I'd also mention that it's a good idea to update to the latest 151.0 dot release - there are a few WebSerial fixes in there, one of which is Windows-specific. Let us know if you're having more trouble, thanks!
