Currently the location of a console.log in a worker won't be source-mapped. I believe this holds for any event occurring in a worker, for example an XHR in a worker won't have a source-mapped location in the network monitor. The main problem here is that source-map-url-service relies on the actor to pass along the source map URL. However, workers don't cause these actors to be created. Test case here: https://tromey.github.io/source-map-examples/worker/index.html Source code here: https://github.com/tromey/source-map-examples
Also see bug 1385032, where source map errors in workers are probably not reported correctly.
