An added benefit to writing the book

As I work on the third and fifth chapters (on accessibility and client-side debugging, respectively), I've found a few new tools and added them to my own list of actively installed tools:

Web Accessibility Toolbar for Opera

I've known about and used the Web Developer Toolbar & Menu for a while, but this takes a huge amount of the features I know and love, and adds in the accessibility analysis features I've wanted for a while now, such as contrast scaling and greyscale rendering.

Opera Developer Tools

A few incredibly useful scripts for working with CSS/XHTML/DOM in Opera:

• DOM Console
• CSS Editor
• DOM Snapshot

Firevox

When I asked about Mac screen readers I could use while writing Ajax examples, David Poehlman pointed me to Firevox, which (once I got past a couple permission issues) installed quite easily and seems to work really well so far. I haven't tested it out extensively yet, but it even has support for WAI-ARIA markup!
