Web Developer Toolbar for Firefox

[JohnBoucher]

If you have Firefox installed , download the Web Developer (http://update.mozilla.org/extensions/moreinfo.php?application=firefox&id=60&vid=63)toolbar. You get a lot of great tools to use. The CSS tab shows linked or inline CSS and allows you to edit it on the page that you have displayed. WOW...Thats cool.
You can show the links paths , image sizes , alt tags ID and Class details and lots more.

I've used it extensively for over a year now, and it is incredibly useful. But there are so many more absolutely incredible extensions out there that you just need to go download (http://texturizer.net/firefox/extensions/)!

I've used it for a month or two now. I don't know how I worked without it.

Go get it now, if you don't have it.

Hm... I used it for a while and... got rid of it again. I just don't care enough. :D
