[PATCH] Proposed Fix

r=me, should we add a `console.assert(WI.settings.sourceMapsEnabled.value)` inside `WI.SourceMap` somewhere, for sanity's sake?  Do we want to do anything for the case where the user disables source maps after having already downloaded and shown them (e.g. in Resources)?

If I'm a naive user debugging JS stuff on a web site, how do I know that I need to enable or disable source maps?

We should eventually do something where when the user toggles source maps it goes and hides / shows source maps stuff, but for now a reload is sufficient.

JavaScript developers should be familiar with the concept of source maps. If they are debugging their own content they should know, if they are debugging random content then its just something unfamiliar they would have to come across. The Web Inspector UI indicates SourceMaps uniquely in a few ways, which may help them recognize it is different.

In other words, learning about Source Maps is not much different than learning about some JS / CSS features you aren't familiar with.
