Yesterday, after months of intense development, Firefox 2.0 was finally released for public consumption.
There aren't major changes to the user experience, but the tweaks they made are well worth the version bump. My favorite feature by far is the built-in spell checking. For bloggers (like myself) this is a beautiful thing - I can now spell check right here in the browser, automatically.
If you are still using IE 6, go download and install Firefox now. If you have the newly release IE 7 (which is a laughable half-ass copy of Firefox) consider trying out it's free, open source, faster, and more friendly competitor.
