Why not just block the ones you think are going to cause problems and
ignore the rest? Most of them are pretty benign anyway.

I'm using Stylish rather than user*.css files, and just
using url (no -prefix) WFM, e.g., @-moz-document url("about:home")

Oops, apparently hit send before finishing typing. I meant to mention
that I'm not using { display : none } -- I'm just restyling the
about:home page.

I'm not sure what you're asking about.

You're right, they don't. To hide the whole page, you could use the
selector * (as I see you're doing below) or body or html.

AFAICS, without a selector it shouldn't work. It's got to be

@-moz-document url-prefix(about:) {
[selector(s)] { [stylerules] }
}

I see from the other thread, it's editing tables. It looks like that
functionality is behind a login, so I can't look at it. So,
unfortunately, I can't guess why hiding everything on about: pages
breaks it.
