ABSOLUTELY LIFE CHANGING - AUTHOR SHOULD BE SUPPORTED FOR THIS ONE!!! Rated 4 out of 5 stars

This add-on is truly one of those change-your-life-for-the-better type of apps. Keep in mind it is free, and it has it's bugs(configuration is a little difficult), and it still needs a little work, so backup your css every now and then, and be prepared to lose any comments in your css, but it makes CSS authoring just an AMAZING experience, you see your changes instantly, and save instantly. once you learn it's few disabilities, it may be the single most useful html tool I have ever used, right up there with eclipse PDT. I give it 4 stars instead of 5 because, the development has a little more to go, but this is a MUST-HAVE extension!!!

This review is for a previous version of the add-on (0.9.0.1-signed).
