Site originally by David Winterbottom (user root).

Psst. Open beta.

Wow, didn't really expect you to read this far down. The latest iteration of the site is in open beta. It's a gentle open beta-- not in prime-time just yet. It's being hosted over at UpGuard (link) and you are more than welcome to give it a shot. Couple things:

  • » The open beta is running a copy of the database that will not carry over to the final version. Don't post anything you don't mind losing.
  • » If you wish to use your user account, you will probably need to reset your password.
Your feedback is appreciated via the form on the beta page. Thanks! -Jon & CLFU Team

I've been using

killall firefox-bin

since Firefox 1.5ish, never had a problem.

As one of the commenters on your blog wrote, starting with Ubuntu Hardy Heron, the command is simply:

killall firefox

I'm not sure how related this is to the distro or Firefox version, but apparently that's the case.
