[Greenguy]

Let's help each other out by sharing some of our interesting/useful Firefox browser apps/extensions. Whether they're work related or not, post what you're using (with a link) and maybe find one that you didn't know about |shake|

I keep my list of add-ons short. These three are all I use, but I'd be lost without them.

1. Web Developer Tools - http://chrispederick.com/work/web-developer/
2. Snap Links - http://snaplinks.mozdev.org/
3. Form History Control - http://www.formhistory.blogspot.com/

My few pearls:

1) Html Validator: http://users.skynet.be/mgueury/mozilla/
2) User Agent Switcher: https://addons.mozilla.org/en-US/firefox/addon/user-agent-switcher/
3) Spell Cheker: https://addons.mozilla.org/en-US/firefox/addon/spell-checker/

Firefox is my daily workhorse browser.

These are the addons/extensions I have installed.

Web Developer (http://chrispederick.com/work/web-developer/) extension (as Toby mentioned) provides many valuable tools.

DownThemAll (https://addons.mozilla.org/en-US/firefox/addon/downthemall/) lets you download all the links or images contained in a web page in just one click. Helpful in gathering content when zipped files aren't available.

SEOquake (http://www.seoquake.com/) is a seo-tool that shows page rank, Google index, Alexa and many others. Keyword Density tool shows number of times a keyword or phrase appears on a web page. Also can highlight nofollow links.

FireForm (http://fireform.free.fr/en/about.html) is a Firefox extension that automatically fills in forms.
You teach FireForm once, then it fills in forms with just one click.

Live HTTP Headers (http://livehttpheaders.mozdev.org/) adds 'Headers' tab in 'View Page Info' of a web page and a tool in the 'Tools->Web Development' menu to display http headers in real time. Also lets you edit request headers and replay an URL.

Nice, a lot of good ones here. I use Seamonkey and I'm very happy with Flash Got (https://addons.mozilla.org/en-US/firefox/addon/flashgot/)

3) Spell Cheker: https://addons.mozilla.org/en-US/firefox/addon/spell-checker/

I think your Spell Checker plugin doesn't work :)

I really haven't been using any plugins, but some of these sound great! Thanks!!!

Nono... It does. It is just a little bit complicate to make it working... I don't remember how I did, I remember it was not easy...
