Firefox developers plugins
Writing about web page http://www.bytefarmers.com/log/2005/09/03/extending-firefox-for-web-developers/
To add to my usual collection of Firefox plugins, I came across the above webpage listing a few new ones. On top of my existing ones, I've just added:
View Rendered Source by Jennifer Madden
Neat tool that allows to view the actual generated markup, useful when generating markup via scripting.
View Cookies by Edwin Martin
Utility that adds a Cookie tab on the ‘Page Info’ window, allowing you to see and edit any set cookie that affects that page.
ViewCookies is so much quicker and easier than browsing around the standard Firefox cookies menu and the View Rendered Source is lovely for viewing HTML source code.
