Should the source view suggest enabling the "JS Sources" feature?

[mstange]

Now that JS source support has landed in Nightly, I tried it a few times but it wasn't working. On the third try I finally remembered that I need to enable a feature on about:profiling. I would have realized earlier if the error message in the source view had given me a hint.

Should we add such a hint? Or are we planning to have it work by default soon?

Good idea! Even though we want to have it on by default soon-ish, I think we should still add it. Because I would assume that this feature would be off on some presets (like networking). It's still good to give some hint for cases like that.
