Development Firefox Extensions

In my working life, I work as a web developer. In my tireless search for tools to help in this endeavor I use some absolutely invaluable Firefox Extensions. Most people that work in the field will probably know about them, but I figured I would post something with links to the extensions I use. Let me know if there are others you use which I have missed.

Bookmark Sync and Sort – connect to an FTP/WebDAV server and synchronize your bookmarks

Deepest Sender – (OK, not really development software, but great for posting to WordPress without needing to explicitly log in to WordPress.com) post to blogs from directly within Firefox

Dowload Statusbar – View and manage downloads from a tidy statusbar – without the download window getting in the way of your web browsing.

Firebug – edit, debug, and monitor CSS, HTML, and JavaScript live in any web page

FireFTP – secure, cross-platform FTP client

GoogleTabs – open Google search results in tabs

HTML Validator – adds HTML validation

IE Tab – see how your webpage displayed in IE with just one click and then switch back to Firefox

Stylish – User styles empower your browsing experience by letting you fix ugly sites

Web Developer – Adds a menu and a toolbar with various web developer tools

P.S. If you don’t have Firefox yet, go get it now! :p
