Mozilla shipped its Firefox 15 just few days ago, and now in their Beta channel Firefox 16 got updated with one amazing feature for developers. The Developer Toolbar now has a command line for your favorite browser.
The command line gives you quick keyboard control over your tools and access most of the Firefox features just by typing in the command line.
The command line is designed to be quick-to-type and discoverable. This means it would auto complete most of the commands for you, saving more time.
Watch the demo video, am sure you would be impressed
