Here are some extensions I've found to be very helpful in a lot of the web development I do, some of which I incorporate within ExtremeTech. I have to admit, many of these extensions won't come as a huge surprise to developers already acquainted with Firefox extensions, but hopefully there will be some you've never seen.
Web developerWeb Developer should be your first stop if you're going to build a library of extensions, largely because it is many extensions in one, offering tools like image and form debugging, HTML and CSS validation, windows resizing, and much, much more. If your Web site has a mixed blend of source code, this extension easily locates CSS, Javascript, and so forth. Once you've finished punching code into your editor, you can connect directly to the W3C to ensure that your code is clean and XHTML compliant.
SeoQuakeSeoQuake allows webmasters to measure how effective their site is under the RADAR of important search engines. This extension is primarily two-fold: It offers a toolbar that displays information on whatever page you're visiting by displaying Google's page rank status, Yahoo status, and other SEO parameters; and it also allows the same data to display within search results, offering an easy comparison among similar sites. It's easy to toggle on and off if you don't want the extra information to appear when you run a search or visit other sites. Also check out SEO for Firefox and Alexa Sparky Toolbar.
LinkCheckerIts name says it all. Run LinkChecker on a Web page and the extension will color code every link: green for good links, red for broken links, grey for skipped links. This is a must for webmasters who are maintaining their sites, and developers should make a habit to ensure all links are good before publishing their content.
264 links on ExtremeTech's home page. You think I'm going to check them all manually?
FireFTPWebmasters in search of a Firefox FTP client don't have to look much further than FireFTP. FireFTP looks and acts just like your more average FTP client, but with added convenience and tools. In addition to uploading content to a remote server, you can also sync directories while you navigate, edit remotely, use SSL encryption, and so forth.
IE TabNo matter how much you love Firefox, Internet Explorer is still the most widely used browser today, especially among noobs. Rather than open up IE to see how well your site renders, you can download IE Tab and have it run directly from Firefox.
View Source ChartNot all of us work with WYSIWYG editors, which means that scanning through long lists of code is inevitable. View Source Chart color-codes HTML tag boundaries to help users quickly scan snippets of source code, define the tag nesting order and hierarchy, and minimize nested elements. This tool would have been a godsend during the early days of HTML coding.

GreasemonkeyGreasemonkey allows users to hack the web with JavaScript. Basically, by writing or installing pre-existing userscripts (JavaScript code others have written), you can tweak the look and behavior of Web sites to fit your preference. Not a fan of Intellitxt contextual popups? Then just write or download a userscript that eliminates them. There's a compendium of these user scripts out there, removing things like banner ads from sites and so forth.
CodetchCodetch is essentially a super lite WYSIWYG editor, straight from your Firefox browser (or separate if you don't want to bog down Firefox). Users can edit HTML directly and preview it. There's also a suite of various validators to ensure your code is clean.
HTML ValidatorThough several extensions offer HTML validation, they don't go as far as HTML Validator. This extension is based on Tidy and OpenSP, originally developed by the W3C, and runs through code to identify any HTML errors, some of which HTML Validator can fix itself. Users can quickly view an icon at the lower right of the screen to see just how compliant a site's source code is. When HTML Validator views the source code, its lists each error and warning, and also highlights those erroneous lines of code.
FirebugFirebug is a bit like Web Developer in the sense that it provides an array of tools at your fingertips. If you deal with CSS, HTML, Javascript, you can easily tweak and zero in on that data without difficulty. You can instruct Firebug to open a pane at the bottom of the current window, or open a new window, and work from there. This is no doubt a useful tool for the experienced developer and it has earned a great reputation.
