Definitely. I just wish they would make some changes so that we can use the "70's style command line" more with Firefox. In other words, options and arguments we can pass to Firefox (the xulrunner app) via the Linux/BSD/OSX/Windows commandline.
For example if I have Firefox running in Xvfb it would be nice to be able to issue remote commands (an early version of Mozilla did have something like this if I recall correctly: -remote), such as the commands they are implementing for this "graphical command line". It would be convenient to easily dump screenshots to image files without having to run something like Crowbar.
Anyway at least they are starting to acknowledge that not everyone uses a mouse or prefers using a trackpad over hitting keys. I mean keys as tactile buttons, not images of onscreen keyboard, like the iPhone or iPad.
