… as recommended by readers of Planet PHP 
Most Recommendations
There were six Firefox extensions that folks repeatedly recommended …
- ColorZilla – advanced eyedropper, color picker, page zoomer and other colorful goodies.
- FireBug – live DOM & CSS inspector. The single greatest web developer add-on for Firefox.
- Live HTTP Headers – view HTTP headers of a page and whilst browsing.
- Web Developer Toolbar – adds a menu and a toolbar with various web developer tools.
- YSlow – Yahoo’s tool for analysing web pages and telling you why they are slow. Requires Firebug.
- Zend Studio Toolbar – debugging assistance for Zend Studio 5.5 and earlier. Isn’t mentioned on the Zend Studio 6 pages, so does that mean it is now obsolete?
… and after that, there was a lot of variety amongst the other extensions that were recommended.
Also Recommended
- Cache Status – easy cache status & management from the status bar.
- ChatZilla – IRC client for Firefox.
- Duplicate Tab – clone a tab along with its history.
- Edit Cookies – edit your cookies right in Firefox.
- Fasterfox – performance and network tweaks for Firefox.
- Firefox Accessibility Extension – test your web pages for functional accessibility features based on the iCITA HTML Best Practices.
- FirePHP – print to your Firebug console using a simple PHP function call.
- FireShot – take screenshots of web pages, and a whole lot more.
- Google Toolbar – Google’s famous in-browser search toolbar.
- GreaseMonkey – customise the way a web page displays using your own Javascript add-ons. See also Lifehacker’s Top 10 Greasemonkey User Scripts, and their Better GMail and Better Flickr add-ons to get an idea of just what can be done with Greasemonkey as a Firefox extension tool.
- HTML Validator – add HTML validation to your browser.
- IE Tab (Windows only) – open Firefox tabs using IE’s rendering engine. See also the popular IE View alternative.
- LocationBar2 – adds additional features to Firefox’s address bar.
- Lorem Ipsum content generator – Generate “Lorem Ipsum” dummy text, for when you need to fill a page with content for testing purposes.
- MeasureIt – draw out a ruler to get the pixel width and height of any element on the web page.
- NagiosChecker – see the status of your services and servers in Firefox’s status bar. You do monitor your servers, right?
- PrefBar – power user toolbar for Firefox.
- Regular Expressions Tester – testing tool for regular expressions with colour highlighting.
- RefSpoof – easy spoofing of the HTTP referrer header.
- ReloadEvery - reloads a web page every so many seconds.
- Save Session – save your current browser windows & tabs for the next time you open Firefox.
- Scrapbook – save web pages locally and easily manage collections. (Like OS X web archives, as supported by Together, DevonThink, and so on, but cross-platform).
- Selenium IDE – record, edit and debug tests for Selenium, the automated UI testing tool for web developers. See also PHPUnit’s support for Selenium. You do have reproducible testing for you web apps, right?
- Stylish – fix ugly sites, customise the look of your browser or mail client by using your own CSS files. Stylish is to CSS what Greasemonkey is to Javascript.
- Tab Mix Plus – tab management on steroids.
- Tamper Data – view and modify HTTP/HTTPS headers and POST parameters.
- TimestampDecode – treats the selected number as a timestamp and displays a decoded date/time.
- TitlebarTweaks – tweak Firefox’s titlebar text.
- User Agent Switcher – Adds a menu and a toolbar button to switch the user agent of the browser.
- Venkman – Javascript debugger for Firefox.
Stu’s Recommends
To round off the list, here are a few extensions that I find useful, but which weren’t recommended. If you haven’t heard of these before, give them a try.
- Flagfox – display a country flag in the status bar for the location of the current website’s server.
- Server Switcher – easily switch between development and production servers.
- Show MyIP – display your current external IP address.
- SQLite Manager – Manage any SQLIte database on your computer.

Well if i install all i think my firefox will get a bit “FAT” so he might be slow and get heart attacks easily

True, but you can always install, disable and just enable when the need arises on a development task

Great list, I’m trying them all!

@Johny:
I’ve got about 15 of the ones listed installed plus about 7 that aren’t and FF loads pretty well on my machine. I’ve not seen too many crashes, either.

Firefox 3 comes out tomorrow, I hope many of these extensions get updated…

Nice list! One I use a lot is Cookiepie (www.nektra.com/oss/firefox/extensions/cookiepie/), seems to be missed here!
Is really useful to log in into multiple accounts in a same site (like Gmail, and others)
Cheers!

I haven’t found a better cookie plugin than Firecookie. It’s a plugin for Firebug. https://addons.mozilla.org/en-US/firefox/addon/6683
