The source map url service allows parts of the codebase to subscribe to get notifications when the filename/line/column of a particular location changes. This happens when a sourcemap loads and causes the location to change from an original to generated location. It also happens if the pref is toggled off because then all of the sourcemap-based locations need to be cleared.

Unfortunately, right now many places that subscribe to these notifications do so using the url of the generated source file instead of the actor ID, which means that if the same file gets loaded multiple times, or an original source file shares the same URL as the generated source file, the debugger cannot know which file it is being asked to open.

Making this work fully for JavaScript files is going to be blocked on https://bugzilla.mozilla.org/show_bug.cgi?id=1641121, but for now, we can at least get the URL service updated to support IDs, and get the CSS viewer/editor panes updated to use IDs, since they all work directly work stylesheet actors and are guaranteed to know the actor IDs, so that's what this issue will focus primarily on as an end goal, though I'll get as much of this done for JS files as I can.
