Joe Hewitt came on-campus today and gave a presentation on FireBug. I use Firebug all the time, but it turns out that it’s chockful of features that aren’t in the docs.

Besides using the search box to do things like filtering for event types and other strings, you can also filter by CSS selector. That’s insane – insanely useful! Also, 0.4 not only brings back copyable URLs, but also lets you launch an URL in a new tab with a CTRL/middle-click.

Joe also went through the new debugger and mentioned how to use that for conditional breakpoints.
