Firefox development toolbar

A friend recently pointed me to a useful development toolbar for Firefox. It’s similar to the development toolbar here but does even more stuff.

Debugging Javascript in Firefox

I’ve recently been trying to make some of my scripts work with Firefox 1.5 (from IE) and I was looking for some debugging help to set me on the right track. I found this tool which seems to work very well: http://getahead.ltd.uk/ajax/venkman.

It’s an updated version of Venkman fixed to work with Firefox 1.5.

One of the things it helped me find is that whereas in IE if I ask a table cell (TD) for the nextSibling and get the next TD, in Firefox you always seem to get a text node first and then the next TD. Similarly for getting the next and previous rows.
