Here’s a page I’ve been meaning to do a long time ago, if you’re a web developer you might want to bookmark it so that next time you set up Firefox +1.5 you’ll have direct links to all the web developer tools you’ll ever need.

• Download Them All (A very simple to use and fast download manager for firefox. Download all files on a web page in one click)
• FoxMarks (Keep your Firefox bookmarks synced in several computers)
• PicLens (Browse all images in a page in Full Screen 3D mode)
• Web Developer Extension (Best extension ever)
• FireBug (All of the tools you need to poke, prod, and monitor your JavaScript, CSS, HTML and Ajax are brought together into one)
• X-Ray (Shows html tags along the page)
• View Source Chart (Displays source code in a friendly easy to follow manner)
• JSView (See the source code of external javascript references)
• JavaScript Debugger (An improved javascript debugger
• CSS validator
• HTML validator
• RSS validator
• del.icio.us (Add bookmarks to your delicious with a right click)
• IE Tab (When you’re testing on Winslow, this comes in handy, no need to open IE anymore)
• MeasureIt (Ever wanted to measure how long an image, or a table is?)
• LiveHTTPHeaders (Wanna see those HTTP/HTTPS headers?)
• FireGPG (Use GPG Signatures in your GMail)
