Web Developer Extension
Quite possibly the handiest web developer extension you'll ever use.
Web Developer Extension by Chris Pederick. I am still wondering how I made it without this tool.
It's been through a few versions, and gets better each time. The Web Developer Extension can be found at Chris Pederick's web site.
Here is a quick list of my favorite features of the Web Developer Extension for Firefox:
- The tag outlines. This lets you highlight live on any page you are viewing the html tags of your choice, or groups of tags. This gives you a sort of x-ray vision for your sites to see how your elements ar interacting.
- Quick access to several 3rd party tools such as and HTML validator, CSS validator, Download speed checker and more.
- Edit CSS on any site and see the changes it would make. This is amazing for checking quick changes on a live site without the possibility of screwing up your design and everyone noticing.
- Over 130 features that are all easy to access and use.
- Detailed cookie information
- HTTP status information
Download Web Developer Extension and try it out. it is 100% free. Works in Mozilla / Firefox / Flock. A great tool that is always available and easy to use.
