For a developer, which browser they use is very important. Another important obstacle in their way is the addons. Some browsers do not allow certain things, so the best way for a developer to get what they want is through addons. I want to get an idea of the variety of developer addons there are for different browsers. To start this topic off, here are some Mozilla Firefox addons I use frequently:

* Firebug 1.4.2
* Clear Cache 1.1
* ColorZilla 2.0.2
* GridFox 1.2
* No Script 1.9.9.01
* Web Developer 1.1.8

i use the following FireFox addons

Web developer 1.1.8
Colorzilla 2.0.2
Measureit 0.3.9
Fireshot 0.78
Font Finder 0.5

Is the Font-Finder app just for font-family or can it pick up font's from images? I doubt it's able to pick out fonts from images, so it sounds a bit useless considering we can pick out the font from CSS anyways. Is it useful at all?

no it wont work with images i just use it to find fonts quickly by highlighting any text on a webpage rather than having to go through the CSS it has quite a bit of info about the text here's a screenshot

Well I use Firebug anyways. The CSS function from firebug picks up all this info easily.
