What are the best add-ons for Firefox?

those most useful for webmasters

[annej]

I know some people have Firefox add-ons that they find helpful for site development but there are so many that I don't know which ones would really be useful.

[phranque]

DOM Inspector 1.8.1.4
Html Validator 0.8.3.9
Live HTTP Extensions 0.13.1
Web Developer 1.1.4
Quick Locale Switcher 1.6.1
Modify Headers 0.6.0

No Script.....Essential for seeing how well sites degrade when faced with Javascript restrictions.

Firebug

ColorZilla is amazing. It's the one best developpment tool that I'd recommend.

Personally I find firebug is just too hard to manage, hasn't grown on me. Either it can't do some things I want it to, or I just don't know how to use it good enough.

JSview: VERY handy if you look at other sites often. I mostly use it for CSS viewing, since it can view both attached JS and attached CSS. Handy, since you'll not need to view source.

CSS viewer is nice too... I have a few dislikes with it (like with font size, it just calculates it in pixels, instead of displaying em or pt values), but it's quite useful if you want to know info on any element (such as margin,padding, and border information on an element, what fonts are used, dimensions, etc.) in your page, good for verification or debugging.

Wow, Thanks for all the suggestions. Where to start? I especially need to be able to check my code as I hand code my HTML and CSS. Looks like there are other things that will be helpful too.

Vanessa Fox listed a bunch only a few days ago.

I have 22 loaded at present.

Some are only used a few times per month, others many times per day.

I reckon FireFTP is right up there with colorzilla as my favourite extension.

FireFTP is a good program, bit it really hangs and is sluggish overall on my vintage Win98SE system, so I decided to delete it. I also do not like the fact that it does not save whatever window sizing changes that you make.
