Hey there,

I found a great Firefox extension that is worth it!

Have a look at this partial screenshot:

For example, it allows CSS edit on the fly and see changes directly: no reload/upload necessary! Adjust your style, then save and put live, isn’t that wonderful?

You can also play with privacy, display image information, div, frames, validate Links on the page, and many other interesting things.

Looks like I found a new friend 😀
