I'll see what I can do when I get an opportunity. I installed it and tried it, but since I didn't have time to really dig in, I uninstalled it after the first sanity pass failed. This was Firefox 115.02 (64-bit) Windows 10.

Wish it would work for me. It's a good idea, but C-n and C-p just bring up a new page and print dialog respectively.

If I understand right, this is a clarification (of sorts) to the standard of "true threat". Ken White covers a lot of first amendment speech issues and has a very good explanation here: https://popehat.substack.com/p/supreme-court-clarifies-true-threats

So. To the practitioner, or to the internet tough-talker, what does this mean? It means that the law of the land, at least 7-2, is that a threat is only outside the protection of the First Amendment if:

• A reasonable person, familiar with the context, would interpret the threat as a sincere statement of intent to do harm, and
• The speaker was reckless about whether the threat would be taken sincerely — that is, they “consciously disregarded a substantial risk” that it would be taken seriously.
