Firefox 2 was released recently and offers a slew of security and
performance improvements. The main user interface change I’ve noticed
is tabs now have their own button to close them, rather than using the
"master" close tab icon that was on the right in earlier releases.

you aren’t using the Firefox web browser yet, WHAT’S WRONG WITH YOU!!!
🙂 It really is way better than Internet Explorer. And it’s FREE!

Get it here, or upgrade if you have an older version.
