This can be useful when browser inspectors (Firebug, Chrome) won’t do.

Fiddler is a Web Debugging Proxy which logs all HTTP(S) traffic between your computer and the Internet. Fiddler allows you to inspect traffic, set breakpoints, and “fiddle” with incoming or outgoing data. Fiddler includes a powerful event-based scripting subsystem, and can be extended using any .NET language.

Fiddler is freeware and can debug traffic from virtually any application that supports a proxy, including Internet Explorer, Google Chrome, Apple Safari, Mozilla Firefox, Opera, and thousands more. You can also debug traffic from popular devices like Windows Phone, iPod/iPad, and others.

Web Developer Google Chrome Browser Extensions

Here are some Chrome browser extensions that are really useful for web developers:

  • JSONView
    Validate and view JSON documents
  • PHP Array View
    I couldn’t find a PHP array prettifier but if you var_dump a PHP array and inspect it in Chrome, it’s pretty.
  • PageRank Status
    Shows Google PageRank and AlexaRank of current web page, quick access to Geo IP Location, Whois, Alexa, backlinks and indexed pages
  • Show Title Tag
    Shows title in top of the page, since you cant read the title in the small tabs.
  • Rulers, Guides, Eye Dropper and Color Picker
    For UI developers. Pick any color from webpage using eye-dropper tool; display rulers, guides and grid on the page.
  • Page Ruler
    Measure any distance on a page

Quick Disable Javascript / Cache in Chrome

When updating a website, you may sometimes notice that your changes don’t go into effect when you refresh your screen (F5). You also will want to test your site to see how they look with Javacript turned off.

To refresh your page, you can hit F5, but you may not see any changes since content may come from your local cache.

To force your page to be reloaded from the server regardless of your local cache, use Shift + F5.

To turn on/off javacript / local cache in Chrome, see the image below.

IE-Specific CSS / Javascript

As well all know by now, IE (Internet Explorer) is a problematic browser for all web developers. There will come a time when everything just looks great everywhere else (Chrome, Safari, Firefox) but NOT in IE. If you can’t make your CSS, Javascript to work in all browsers including IE, you can add a separate CSS and Javascript file that works only in IE using the following code:

<!–[if IE]>
<link rel=”stylesheet” type=”text/css” href=”/asset/stylesheet/ie.css” />
<![endif]–>

<!–[if IE]>
<script src=”//html5shiv.googlecode.com/svn/trunk/html5.js”></script>
<![endif]–>
