13 Great Firefox Extensions For Web Professionals
Like most web developers or SEO professionals, I use a vast array of tools to get the job done. I use a
combination of desktop and web applications, some purchased and some free. Everyone I know has
downloaded a free copy of Mozilla Firefox, but few realize that by installing some of the 1,500 free
extensions they can eliminate the need for most of the other applications they currently use. Below are my
13 favorite extensions for web professionals (in no particular order):
HTML Validator (http://users.skynet.be/mgueury/mozilla/) – validates web pages to the W3C HTML
standards with a simple green check in the corner of the page if the page validates, a red check if it doesn't,
and a yellow exclamation point if there are warnings. It also includes an enhanced view of source code that
allows you to see where errors are within the code.
FireFTP (https://addons.mozilla.org/firefox/684/) – free, secure, cross-platform FTP client that provides easy
and intuitive access to FTP servers. This eliminates a piece of software for those of you who use a separate
program for FTP.
Professor X (https://addons.mozilla.org/firefox/2823/) – lets you view header information without having to
view source code. The page "slides" down and Professor X shows you the contents of the page's head
element, including Meta, Script and Style content.
NikkelWHOIS (https://addons.mozilla.org/firefox/2646/) –view the WHOIS information for any page by
clicking the button on the top-right of the browser.
IE Tab (http://ietab.mozdev.org) – sick of swapping between Internet Explorer and Firefox when testing out
a web page you're developing? With IE Tab you can view Internet Explorer in a Firefox Tab!
FireBug (https://addons.mozilla.org/firefox/1843/) – an advanced debugger console that lets you monitor
your JavaScript, CSS, HTML and Ajax.
Codetech (https://addons.mozilla.org/firefox/1002/) – web page editor that has the feel of Dreamweaver. An
amazing extension for anyone doing web design that doesn't want to fork out a few hundred dollars for
Dreamweaver.
Server Switcher (https://addons.mozilla.org/firefox/2409/) – easily switch between sites on your development and
live servers by clicking the switch server icon.
SEO for Firefox (http://tools.seobook.com/firefox/seo-for-firefox.html) – pulls useful market research data right into
Google's and Yahoo!'s search results, including Google PR, Age, links, Alexa rank, WHOIS, and more. It also adds a
few helpful links to the top of the search pages, including Google Trends, Google Traffic Estimator, and the Overture
View Bid tool.
Yet Another Window Resizer (https://addons.mozilla.org/firefox/2498/) – allows you to resize browser window to
default screen resolutions.
AdSense Preview (https://addons.mozilla.org/firefox/2132/) – preview the Google AdSense ads that would appear
on that page. This is incredibly useful if you are considering putting AdSense on a page and don't want to go through
the hassle of signing up for an account and putting the ads up just to see what type of ads will show.
Screen grab (https://addons.mozilla.org/firefox/1146/) – takes a screenshot of the webpage and saves it as an image
file. This saves a ton of time compared to the method I used to use – take a screenshot and open Adobe Photoshop
to crop the image.
Server Spy (https://addons.mozilla.org/firefox/2036/) – indicates what brand of HTTP server (Apache, IIS, etc.) runs
on the visited site on the lower-right side of the browser.
