With major new versions of Firefox and Chrome rolling out every few weeks, it's easy to tune them out. Believe it or not, though, the latest Firefox release actually has a couple of noteworthy new features.
First are the new developer tools, which replicate the functionality of the popular Firebug extension and similar tools built into Internet Explorer, Chrome, Safari, and Opera. Those tools proved particularly invaluable when I was working on TR's new design, since they let me test tweaks to our CSS stylesheet and see results applied on the fly, all without making permanent modifications. (There's much more to Firebug and its ilk than that, of course.) Google snatched up Firebug developer John J. Barton last year, which presumably motivated the folks at Mozilla to produce their own alternative. And here it is:
I've gotta say, it doesn't look half bad, even if it only seems to have a fraction of Firebug's functionality. I suppose Mozilla had to start somewhere, though.
Also worthy of note is Firefox 10's support for full-screen HTML5 apps. That means HTML5 video players, including YouTube's, can finally run in full-screen mode just like Flash—a big deal for sure. Oh, and Mozilla says that, as of Firefox 10, "most add-ons are now compatible with new versions of Firefox by default." Check out the release notes for more details.
