16 useful and important Firefox extensions for SEOs, Developers and Other Users.

Here I have listed 16 useful and important Firefox extensions for SEOs, Developers and Other Users.

Long time I haven’t post anything about external sites in my blog.

Finally, after a long time of every day work shit, I managed to write something, today I’ve come up with some tools and tips which are very useful for SEOs, web designers and developers, like most website designers, developers and SEO experts, I use a vast range of tools and widgets to get the job done, few of them are desktop applications and few are web applications, few are paid and few are absolutely free and some are partially free. Below are few of my favorite add-on

HTML Validator – HTML Validator checks pages from within the Firefox web browser and validates web pages to the W3C 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 gives an enhanced view of source code that allows you to see where errors are within the code.

FireFTP – It is free, secure, cross-platform FTP client that provides easy and spontaneous access to FTP servers. It removes a piece of software for those of you who use a separate program for FTP.

Professor X – Professor X lets you analyze header information without seeing 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 – NikkelWhois lets you view the WHOIS information for any page by just clicking the button on the top-right of the browser. It is WHOIS lookup that adds a small WHOIS button next to your URL go button.

IE Tab – IE Tab embeds Internet Explorer in a Mozilla/Firefox tab. This is derived from the famous extension IE View, so if you are sick of substituting between IE and Firefox when testing out a web page you’re developing, With IE Tab you can view Internet Explorer in a Firefox Tab!

FireBug – IT is an advanced debugger console that lets you monitor your JavaScript, CSS, HTML and Ajax.

Codetech – It is a web page editor that has the feel of Dreamweaver. Its an amazing extension for anyone doing web design that doesn’t want to fork out a few hundred dollars for Dreamweaver.

Server Switcher – easily switch between sites on your development and live servers by clicking the switch server icon.

SEO for Firefox – 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 – allows you to resize browser window to default screen resolutions.

AdSense Preview – 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 – 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 – indicates what brand of HTTP server (Apache, IIS, etc.) runs on the visited site on the lower-right side of the browser.

ColorZilla: Choosing color is always a key point when developing any websites, its an color picker with which you can get a color reading from any point in your browser, quickly adjust this color and paste it into another program. ColorZilla is a very useful add-on for Firefox and a must for web designers. You can pick color code for any point in the browser window, it lets you zoom the page you are viewing and measure distances between any two points on the page. The built-in palette browser allows choosing colors from pre-defined color sets and saving the most used colors in custom palettes.

RoboForm: RoboForm is the top-rated password manager and web form filler that completely automates password entering and form filling. This tool is very useful for Link Builders.

Copy as HTML Link: Copy as HTML instead of a normal hyper link. Makes posting links in your blog slightly easier. Not the best extension, but it should be mentioned on the list.
