Most Web developers write for all Web browsers, but their development tools only work on one browser. To the extent that browsers are standard, this works out. Except when it doesn’t. Then you are stuck trying to use the unfamiliar development tools in another browser. Moreover, some browsers have better or different support for development tools.
The world of Web development changed in three years. Other browsers gave up on small independent tools , they now have debuggers that look and act an awful lot like Firebug; there are even another browser now and it comes with a Firebug-like debugger built-in. While I am hardly unbiased, I think Firebug remains the best of the bunch, both in terms of overall design and in terms of a rich and appropriate feature set. For that we have a lot of talented and dedicated contributors to thank!
But what about the next three years? I’ll do a little dreaming in my next post.
