What's the best way to debug a webworker? My worker appears to be failing somewhere, but I don't appear to be able to log things to the console to figure out what's going on. Is there a way using firebug, or webkit's inspector I can run javascript in the webworker context? Is there a better way of doing this?

The Webkit nightlies have web worker debugging facilities if I recall correctly. – zneak Sep 12 '10 at 16:22

At the moment no browser supports debugging of web workers. I've tested
- Chrome 7.0.517.24 dev
- Firefox 3.6.10
- WebKit nightly r68636
There is a nice article by Nicholas Zakas about debugging web workers.

1This is essentially what I already had. Chrome has a pseudo-debugger for webworkers, but it basically just puts them in an iframe and connects the onmessage/postMessage handlers properly. – Michael Oct 03 '10 at 19:08
