Mozilla Labs has recetly introduced thier new innovation "Bespin" , a web-based text editor speally meant for web developers, as it shows color coding for web based languages.
"Bespin" is based on new technology HTML 5, which so far being implmented only in very few browsers MOzilla firefox 3 and WebKit Nighty. yes it doesn't work in Chrome for now.
This release is still in Alpha.
I still like the look and fill off this web-based text editor.
Worth trying once.
