Difference Between Firebug and Fiddler

In this Article we will some differences between Firebug and Fiddler

Fiddler and Firebug are two different tools that we use to solve two different problems.

Firebug 

Firebug is primarily used to Inspect / Tweak the DOM, script debugging, and basic network information. It primarily deals with things inside the browser.

Some things you would use Firebug for is tweaking CSS styles, trying to figure out where some style is coming from, etc. It can also be used for breakpoints in JavaScript, and basic request / response information such as content, headers, timing, etc.

Fiddler

Fiddler goes much further underneath of it. Fiddler is useful for inspecting network / protocol level information that the browser is doing, as well has a lot of analysis helpers.We typically use this when We are trying to diagnose compression issues, see network traffic, very fine grained details for timing, or making your own requests to the server, which we do when we are tinkering with SOAP / Web Services.
