Although that people doing something very illegal which usually results in long jail sentences aren’t setting it to High makes me wonder how useful this is if people clearly don’t understand the threats.
And it could probably block more things at Low; do SVG animations really need to be on by default? But then that same question could be applied to Firefox itself.
How much rust is in firefox now? How long until we can feel safe using JS?
Rust isn’t magically going to make JS safe. ;)
