I have compiled a list of useful add-ons and tools to share with you all to make your life easier as a web developer:

FireFox:

Web Developer Toolbar - This is the swiss army knife and the all-in-one survival kit for web developers.
FireBug - This is a brilliant addon. It allows you to edit, debug and monitor CSS, HTML, and JavaScript live in any web page.[/url]
IE Tab - IE Tab gives you the option to see what your web page looks like in Internet Explorer.
Screengrab - Screengrab will give you the option to save an entire web page as an image.
Colorzilla - Advanced eye dropper, color picker, page zoomer and a few other useful tools.
Operaview - Operaview is an addon that allows you to see what your web page looks like in Opera.
XML Developer Toolbar - This is a very handy XML Developer's Toolbar.
Link Checker - Use this addon to check the validity of the links on any web page.
FireFTP - This will provide you with a built in FTP client in FireFox.
KGen Keyword Generator - Allows you to see what keywords are strong on visited web pages.
RankQuest SEO - You are only a few clicks away from carrying out most of your day to day SEO.
MeasureIt - Accurately measure any portion of a page that you select.

Nice I have FF and I use FireBug, IE Tab, Operaview, and Colorzilla haha but I also use one that I find useful that you don't have...it''s called MeasureIt. It measures the pixels on the screen of a drag and drop box you make. It comes in handy when making a skin for making a head image or whatnot.

Nice list. I'll sticky this as it will be useful

If you can provide a link to that I'll be happy to add it to the list.

Just a note - XML Developer Toolbar doesn't work for FFv3.
