I would just like to say that this toolbar is AWESOME.

Looks quite similar to the functionality of Chrome's right click -> inspect element.

It can do a whole load more - it allows you to manipulate the page, strip out styling, certain scripts, or view generated source, highlight various things on the page like separators, links to external sites, etc.

Seems the inspect element thing can aswell, you tried it?

Yes.

Try the FF one and you'll be amazed. By comparison the FF tool is incredible.

Heh, I don't actually use it (don't really do web development), was just wondering how it compared really.

Theres a similar thing in GWT if you use that to make JS, but yes, the web developer toolbar is the one thing I missed from FF when switching to chrome. The best feature has to be the show what things affect an element "html > body > div #wrapper > div #header > etc."
