It's not just FireFox that supports this URL scheme - the entire Java world
uses it and supports it back as long as JAR files have existed as far as I
know. While web pages are a different domain it seems silly to have two
completely different notations for the same thing just because of aesthetic

It's also worth noting that the jar: scheme will allow you to target anchors
in a HTML document that's within the archive where as the fragment
identifier syntax would not, unless you used two fragment identifiers:

Why not? It seems reasonable to have some things inside the JAR and some
dynamically created outside of it. For example were Gmail wanting to reduce
the initial download time for it's JavaScript and UI resources it could put
them in a JAR file but the JavaScript would still want to send requests to
retrieve the user's actual mail data. It could use an absolute URL to do it
but why not support relative URLs?

The file system inside a JAR or ZIP is strictly speaking flat, but logically
hierarchical - ie: you unzip it and you get a hierarchy of directories. The
actual method of storage in bits and bytes doesn't seem to matter. Perhaps
I'm misunderstanding your point...
