I had the same experience though I have to admit that some things in Firefox are better these days, like checking where an event comes from, going really deep into objects, referencing other objects, comparing rather big objects.
The only thing I really miss is a view WebSocket frames. In many other cases I ended up preferring Firefox Dev Tools which I think while a bit harder to get into are more powerful.
But that might really relate to what precisely one is doing. I am not a web designer.
The only thing I'm missing in either browser is the ability to ignore jQuery as I'm debugging. Stepping in and out of jQuery (and other libraries like underscore) is a pain.
The Firefox debugger should automatically blackbox minified sources. You can also click on the little eye icon in the debugger panel to manually blackbox sources.
You can also use the developer toolbar to run a command like `dbg blackbox --glob *-min.js` etc. to blackbox a bunch of stuff at once.
