Like most web developers or SEO professionals, I use a wide range of tools to do the job. I use a combination of desktop and web applications, some purchased and some are free. Everyone I know has downloaded a free copy of Mozilla Firefox, but few realize that by installing some extensions of the 1,500 free, they may require in most other programs they currently use to eliminate. Here are my 13 favorite extensions for web professionals (in no particular order):
HTML Validator (http://users.skynet.be/mgueury/mozilla/) – validate web pages with W3C HTML standards with a simple green check mark in the corner of the page if the page is validated, a check or red it, and a yellow exclamation point as warnings. It also includes an improved presentation of the code that you can see where errors in the code.
FireFTP (https: / / addons.mozilla.org/firefox/684 /) – free, secure and multi-platform FTP client that is easy and intuitive FTP server access offers. This removes a piece of software for those of you who use a separate FTP program.
Professor X (https: / / addons.mozilla.org/firefox/2823 /) – Ask your header information without source code. The “sliding” down and Professor X shows you the contents of the main page of his element, including Meta, Script and content style.
WHOIS Nickel (https: / / addons.mozilla.org/firefox/2646 /)-Check the WHOIS information of a page by clicking the right button of the upper browser.
IE Tab (http://ietab.mozdev.org) – sick of change between Internet Explorer and Firefox to test a web page that you develop? With IE Tab you use Internet Explorer in a Firefox tab!
Firebug (https: / / addons.mozilla.org/firefox/1843 /) – an advanced debugger console allows you to monitor your JavaScript, CSS, HTML and Ajax.
Code Tech (https: / / addons.mozilla.org/firefox/1002 /) – Web page editor that has the feel of Dreamweaver. A great extension for anyone doing Web design that will not pay a few hundred dollars for Dreamweaver.
Server Switcher (https: / / addons.mozilla.org/firefox/2409 /) – easily between the sites of your development and live servers by clicking the switch server.
Firefox SEO (http://tools.seobook.com/firefox/seo-for-firefox.html) – draws a useful market research data right into Google and Yahoo search results S, including Google PR , age, links, Alexa rank, WHOIS and more. He also added some links to the top of the search, including Google Trends, Google Traffic Estimator, and a submission tool for Overture.
Yet Another Window Resizer (https: / / addons.mozilla.org/firefox/2498 /) – you can resize the browser window to default screen resolutions.
AdSense (https: / / addons.mozilla.org/firefox/2132 /) – an example of the AdSense ads that appear on this page. This is extremely useful if you plan to put AdSense on a page and do not want to go through the hassle of signing up for an account and introduce the ads just to see what kind of ads.
screenshot (https: / / addons.mozilla.org/firefox/1146 /) – Takes a screenshot of the web page and save it as an image file. This saves much time compared with 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 type of HTTP server (Apache, IIS, etc.) runs on the visited site on the lower right side of the browser.
