If seamonkey is based off a relatively recent version of mozilla firefox, why doesn't CSS "break-after: page" work with print preview for PDF?

InstNEON001: pondering if it's "based off a relatively recent version of mozilla firefox" is not the best way to look at it, it's more like: the "based off" firefox version is at an earlier point, and a lot of changes from firefox have been added on top of that, for features and also the security fixes from Firefox and Thunderbird

InstNEON001: short answer is probably "it wasn't added (backported) yet", this reminds me of a help documentation style change that lacked something to fully apply, I wonder if it's the same thing

Can I have CSS automatically applied when I type a certain character?

In compositor.

Because changing settings to use css styles instead of html attributes doesn't work. Or at least doesn't seem to work.

re: the break: It's possibly related to what I was thinking about, which is bugzilla.mozilla.org/171549

InstNEON001: so a quick test here shows "page-break-after:always" works, but "break-after: page" doesn't, is this what's happening there?

then I'd guess bug 775618

InstNEON001: "when [you] type a certain character?", as a sort of macro? something else?

(sorry, I'm not sure I understand what you meant by that)
