The Mozilla Project has posted the third release candidate of Firefox 2.0. New features in 2.0 include:
- Anti-Phishing Protection.
- Search suggestions now appear with search history in the search box for Google, Yahoo! and Answers.com
- Scrollable tabs
- Ability to re-open accidentally closed tabs
- Better support for previewing and subscribing to web feeds
- Inline spell checking in forms (ironically the first word it flagged for me as misspelled was "Firefox")
- Search plugin manager
- Microsummaries feature for bookmarks
- Automatic restoration of your browsing session if there is a crash
- New combined and improved Add-Ons manager for extensions and themes
- New Windows installer
- JavaScript 1.7
- Client-side session and persistent storage (a really hideous idea, sure to be misused)

It's not immediately clear what's changed since RC 2, but presumably bugs were fixed. I've been using Firefox 2 as my primary browser since beta 1, and it's been pretty smooth over all.
The inline spell checking is indispensable, and worth the upgrade alone.
The restore session option is also quite nice.
The only problem I've encountered are extensions that don't yet support FireFox 2.
