Chris Casciano (of the famed Daily CSS Fun redesigns) has released on the most useful Mozilla toolbars I’ve yet encountered: the PNH Developer Toolbar. Not only does it offer direct links to the W3C’s key Web recommendations (as well as a number of test suites and some Mozilla tools), it also has some hand bookmarklet-like tools. Among my favs: “Disable Styles,” “Apply External Styles,” “Show Window Size,” and “View Source” (which opens it in a new tab).

Meanwhile, the Mozilla folks finally released the browser’s new name. Are you ready?

Firebird.

A lot of people are underwhelmed.
