I suppose Flash could be considered a notable exception there.

Flash was proprietary. Open standards and formats are what we've always kind of expected would keep working.

Yeah, and java applets + some more tech enabled by plugins. But I guess we always considered the "plugin-web" to be "different" in that regard.

IIRC flash was a plugin but it was integrated into chrome install. I don't remember if it was part of FF default install or not, but I can guess it wasn't.
