Spell checker for Firefox 0.9+: this is the first spell checker I've seen that explicitly supports the newer Firefox releases.

BugMeNot for Firefox: It's a Firefox plugin that will help you avoid registration on sites like the NYTimes, LA Times, and other mandatory free registration sites. A useful tool for the compulsive news junkie. I've been using it for a week now and I'm pretty satisfied.
