The other nice thing about FF for devs is that Chrome is a little too robust sometimes. I've had some egregious errors in my markup and Chrome still manages to do what I intended. But then it's broken on every other browser.

As far as I've experienced, anything that runs perfectly in FF runs perfectly in Chrome. But the reverse is not true.

I do wish it had better integration with the web console though. It just seems strange when you pop-up the web console tab to have a JS prompt for entering javascript directly above a Browser prompt for controlling the browser.

It'd be nice if you could just go into a javascript entry mode on the browser prompt itself and see the output appear in the web console. Even something as simple as adding a javascript command where the argument passed into the command is javascript would be useful (perhaps someone could create an add-on that does this)
