“EditCSS Extension for Mozilla Firebird: Very Useful”

If you do any web design, you must try out the EditCSS extension for Mozilla Firebird.

I have quite a few extensions installed, but this is the most useful of all of them. It opens the page's CSS in a sidebar, and lets you edit them dynamically. You don't have to press any buttons or reload the page or anything: make a change, and the page reflects it instantly. What a fantastic way to experiment!

This would have saved me hours during the partial redesign of the admin system in Conversant, which I finished early this week.
