13 Must-Have Add-ons To Strengthen Firebug

Firebug LogoFirebug is probably one of the most helpful tools used when developing websites.

Specially, after JavaScript & Ajax became that much popular, it is hard to findout how we were developing & debugging without Firebug.

This great Firefox add-on, besides the ease of use & continious development by a talented team, has many features that make it a must-have like:

  • working inside browser, no need to switch apps.
  • being real-time, logging every request
  • ability to edit code & see results instantly
  • debugging JavaScript, measuring its performance & more..

It also has another feature, which is extendibility with help of Firefox add-ons.

There are various add-ons that can add more power to Firebug for creating better & faster. Here they are:

 

YSlow

YSlow Firebug Addon

YSlow is a Firebug add-on for analyzing web pages and getting suggestions on ways to improve the performance (parallel with the rules for high performance web pages).

YSlow grades web pages based on the predefined rulesets or a user-defined one . It also provides tools for performance analysis, including Smush.it™ and JSLint.

Page Speed

Firebug Page Speed

Very similar to YSlow, it is an add-on by the Google team for evaluating the performance of web pages and, best of all, getting suggestions (based on "Web Performance Best Practices") on ways to improve them.

Page Speed automatically optimizes images & provides compressed ones foruploading later.

It can also detect  JavaScript and CSS loaded that actually isn’t used for decreasing the total size of these files.

Pixel Perfect

Pixel Perfect

In order to easily find out how a fresh element will look with the design in general, Pixel Perfect enables web developers and designers to overlay a web composition over top of the developed HTML.

It is possible to toggle on/off any number of design elements to see if they fit well or not. And, with the opacity option, HTML below the composition can be viewed.

CodeBurner

CodeBurner

CodeBurner offers a reference panel with a search tool for looking up HTML elements, attributes, and CSS properties.

It also provides shortcuts to view information or code samples about a selected item.

FireUnit

FireUnit

FireUnit provides a simple JavaScript API for doing simple test logging – unit testing and viewing within a new tab of Firebug.

FirePHP

FirePHP

With the help of FirePHP, it is possible to log to the Firebug console by a simple PHP method call.

Data is sent via response headers & won’t interfere with the content on the page.

For any developer who got used to the Firebug interface , this extension is great for PHP debugging.

FireRainbow

FireRainbow - Firebug Syntax Highlighter

FireRainbow adds a better syntax highlighting support to Firebug & has theming support.

FireDiff

FireDiff

It adds a change monitor recording every change made, by Firebug and the website itself, to CSS and the DOM.

This provides a deeper look into the functionality of the website & helps keeping a record of the changes that were required to debug and tweak the page’s display.

Jiffy Firefox Extension

Jiffy

Jiffy Extension, using the Jiffy-Web, adds a new panel to Firebug & generates the visual view of the JavaScript time measurements. It can also output a print-friendly version of the report.

Hammerhead

Hammerhead

It enables you to measure the loading times of webpages.

The extension has support for multiple pages & can clear caches (disk & memory) with a click for a healthier result.

Firecookie

Firecookie

Firecookie, is a cookie viewer/manager that works inside Firebug.

For a faster development, when coding an application using cookies, the panel eases viewing the cookies & their values, expire dates, etc.

It is also integrated with the Net panel & displays both sent and received cookies.

Firefinder

Firefinder

Firefinder offers a way to quickly finding HTML elements matching mentioned CSS selector(s) or XPath expression.

It allows you to instantly test CSS selectors in the page while seeing the content at the same time, and matching elements will be highlighted.

It also shows a count of how many matches there are & lists all the matching ones in a collapsible list in the Firefinder panel.

LiveCoder

LiveCoder

LiveCoder extends Firebug by allowing developers to look at the Firefox chrome.

It is especially valuable to developers building add-ons. LiveCoder’s GUI lets you examine and modify the DOM of any Firefox add-on.

    FireLinkReport – very useful Firebug add-on for on-page link analysis.

  • http://www.jaoudestudios.com Eddie Jaoude

    If you are using yslow & pagespeed, then you can use PageShow, a free online portal to capture your results. This will give you benefit of historic results and comparison and W3c validation.

    The way it works is that yslow & pagespeed have a beaconing facility that sends the results to your private account on PageShow.

    Check it out, all feedback welcome…
