We just changed the way you can inspect objects in the Web Console, check out a Firefox Nightly. For more details you can read:

Also, we have an open bug about clearing the web console after page reload. See:

https://bugzilla.mozilla.org/show_bug.cgi?id=705921

You might want the ability to clear console on page reload as an option. It seems useful and people should be able to enable/disable it (or was it added to new nightly).

Okay, nice. Did you also remove the need for clicking those tiny arrows to expand?

Yes.

I'd go with that.

I can't think of any reason why I'd want to see the information from a previous load - I just want to see what's going on right now, clearly.

I can because I just found that very useful. Think of code that has an error in an window.onbeforeunload handler. By the time the console displays the error the page has switched. Without being able to view the errors from the previous page, this would have been impossible to catch.

I also think that clicking on the link to an error should go to the debugger panel, rather than opening the source in another popup.

This is already implemented in Firefox 22.
