A list of Firefox extensions

I bring up Firefox a lot, I know; but there are so many things that make it great. One thing I love is the ability to add extensions. I thought I would mention the extensions I use, just in case someone is missing out. Since there are like 4,000 of them, let me know if there are others you think are useful. Here’s my list (in no particular order):

1. Firebug – To say the least, a debugger, error console, command line, and inspectors for CSS, HTML, JavaScript, and Ajax.
2. del.icio.us – Post to your del.icio.us account with the click of a button. It’s very easy to tag and edit your current bookmarks. I use this one daily.
3. Google Calendar Notifier – Shows Google calendar events for today and all of tomorrow.
4. CookieCuller – Extended cookie manager that allows you to protect/unprotect certain cookies.
5. HTML Validator – Validates pages as you browse, and puts a little icon down in the right corner. Also, when viewing source, it displays the details (errors and warnings) of the validation.
6. FireFTP – A secure, cross-platform FTP client built right into the browser.
7. Professor X – Let’s you see inside a pages head without viewing the source code.
8. IE Tab – One of my personal favorites. This extension let’s you have a IE tab within firefox, and you can toggle back and forth with one click. This is extremely handy when designing/building CSS templates.
9. Window Resizer – Resize browser window to default screen resolutions. I know the web developer toolbar (next) allows you to resize to variable size, but this is nice for quick, default settings.
10. Web Developer – A must have for web development. This extension has an abundant list of features, half of which I’ve probably never used. Very useful.
11. Save Image As – Adds the ability to save pages, frames, or part of either as an image¹.

¹ Firefox 2.0.0 only

Well, that’s my list of valuable Firefox extensions. I use most of them daily. If you have any extensions that you’d like to share, please do so. I’m always willing to add more.

Update: One more I just installed: errorZilla.
