Dig it: Firefox 2 is here.
Overall it’s a nice improvement over 1.x. There’s no revolutionary new features, but usability and security have been tweaked in plenty of nice ways, making it a worthwhile upgrade.
My only complaint is with the decision to put the "close tab" button on the individual tabs, rather than have a single button over on the right. If you use tabs heavily, it’s nice to have that button in a consistent place, rather than have to mouse from tab to tab to close a bunch of them.
But it turns out that it’s easy to change that back to the old Firefox 1.x way just go to about:config, find the "browser.tabs.closeButtons" preference, and change its value to "3" (no quotes, just the number). If you ever decide to go back to close-button-on-the-tab, just change it to "1".
If you’re still using IE (shudder), what on earth are you waiting for? Get Firefox and enjoy a better, safer Web!
