Firefox Extensions for Developers.
Firefox is my number one tool for web development. I could live without Dreamweaver, but not Firefox. In fact, syntax coloring in the source code viewer is the original reason I started using Firefox a few years ago. Once I discovered all of the marvelous add-ons and tab-based browsing, I switched from IE permanently. Here are many of the add-ons that I use for web development.
- There's the Web Developer toolbar, and Firebug of course. But you already know about those, don't you?
- FireFTP - a fully capable FTP client, which can store settings for multiple. What more do you need?
- Live HTTP Headers displays header information for webpages. That's the sneaky, secret webpage stuff like redirects, form submission info or status codes like 200 OK.
- YSlow will analyze webpages and recommend speed improvements. It requires Firebug, but all you developers have that installed, right?
