Mozilla is great for debugging Javascript...

[X_Caffeine]

Many javascript programmers consider Mozilla to have a buggier javascript implementation than MSIE; what they don't get is that MSIE is very good at interpreting buggy code, which leads to... well, bugs and incompatibility. Mozilla forces you to do it the right way, which leads to greater compatibility in the grand scheme of things.

I wish this article had addressed the whole MSIE "document.body" mess, though. The correct DOM equivalent is "document.documentelement", but it doesn't work in MSIE6 unless the document is properly defined with a DOCTYPE declaration (otherwise MSIE is in backward-compatibility/buggy mode).

Otherwise, a really great introduction. I've been using Mozilla to do javascript for months and didn't know most of the data here.

Feature requests

I agree that HTML highlighting is great, but I've been meaning to post a feature request on bugzilla for some time: let me view-source in a tab, rather than open a new window. That should be really easy to do. I'd also love to have keyboard navigation between tabs (ok, it's probably there already, or at least in Phoenix, but I haven't found them yet..)
