Question

Can anyone suggest some good browser add-on tools/extensions to help with development? I have firebug installed in Firefox which is great for dealing with CSS, HTML and javascript; any other suggestions?

Firebug

Answer 1

Firefox:

• Inspect This if you use the DOM Inspector at all
• Measure It for telling you pixel distances (if you need that)
• IE View or Safari View for ease of testing in other browsers
• HTML Validator if you care about validation
• Console² to improve your js error console
• The Javascript Shell bookmarklet is also handy (and look at the others there as well)

Edit: This is in addition to the Web Development Toolbar mentioned by others
