I don't want to write a complete script for this; there must be some simple way to download source maps. By this I mean go to a website (assuming it has source maps) in Firefox, open Developer Tools, then the Debugger pane, then the Sources. I'd like to download the files shown there.
It doesn't seem like there is a way in Firefox's UI to do this. I tried HTTrack, but it didn't download source maps. I tried copying the index request from Firefox's Network panel as cURL, but it just showed the index.html contents in stdout.
I've found this article that leads me to this tool: https://github.com/denandz/sourcemapper, but it only extracts source maps from a single js file at a time.
