hacks.mozilla.orgNice. I ran into this issue a few months ago:

Nice to hear it works now without the very hacky work around
woohoo! let's get web bluetooth too!
Sweet!
Whelp time to figure out how to disable it or patch it out.
why? Web Serial is one of the better web-based integrations out there. There is no functionality available without an explicit authorization, all that website can do is to pop up a dialog. And you approve individual port on per-site basis, so it's not like it can grab a random port without your knowledge.
This is my favorite model for web: anything more complex should be gated behind user permission. A site which requires that functionality will get that permission with no problem, and a random clickbait fingerprinter will get nothing.
As others have said, you'll get a dialog if any site actually tries to use this. But if you want to fully turn it off, just set "dom.webserial.enabled" to false in about:config (and restart Firefox)
Should be a single click just like with all the other permission based stuff.
