When I fired up Firefox again on restart, the browser told me that it had detected an abnormal shutdown and asked me if I want to restore my previous session? I clicked 'Yes' and up popped all nine Firefox windows I had open prior to the reboot, including one with the full text of what I had written in an unsaved blog post. I ended up having to reboot the system by holding down the power button on my PC. I installed a copy of Firefox 2.0 that I'd gotten from a group of Mozilla folks I met with about a week ago, and on Sunday I was putting together a blog post when another application suddenly froze up and seized close to 100 percent of my computer's memory usage, rendering the machine more or less unresponsive. I personally experienced one of Firefox's most practical new features - the ability to recover from crashes that unexpectedly cause the browser to shut down. Firefox 2.0 includes the lethal X inside of each tab. Tabbed browsing - a component that Mozilla pioneered which allows you to quickly switch between multiple Web sites within the same program window - received a nice touch: It used to be that you had to click a red 'X' at the rightmost edge of the browser screen to close a tab, and more than a few times I clicked the X while focusing on the wrong tab.

If you've been using Firefox for a while now, you might not notice too many surface differences in the new browser.
