't Bijstere spoor

And now for something completely off-topic. Which firefox extensions do you use? I'm mostly interested in the extensions that help web development in one way or another.

• Firebug - Anyone who is into web development, and not using firebug should be hit the face with a stick or something pointy.
• NoScript - If you are a web developer, you know you can't trust 90% of the other developers on the web. This extension prevents you from suffering from other peoples mistakes. As a bonus it also works like an ad-blocker. Because most ad-solutions use flash and/or javascript, you can easily block out certain domains.
• Web developer toolbar - Easy access to a lot of web developer tools. A lot of the features can also be achieved with Firebug, but I still like this one, because most tools are 2 clicks away.
• Whatmon - Monitor whatever. This is a really small extension that allows you to display a status of "whatever you want". All it takes is to generate a tiny XML document and you'll have it up and running.

Aesthetics

• Stop or reload - Merges the stop and reload button, because you never need both at the same time.
• Growl download notification - I like growl for all notification-style messages and I try to find plugins for every program it might be useful.
• History submenus - For a safari-style history menu.
• OS/X favicon theme - This firefox theme is exactly like the default firefox theme, except that it displays favicons in your bookmark toolbars, like on Windows and Linux.

Seems like there might be a chance that FFmpeg will support the proprietary FLV Nellymoser codec within the month.

For those of you that don't know. Nellymoser is the codec used by the flashplayer and FMS to record audio from a users' microphone. Up until now the only place where you could ever replay these streams were in the flashplayer itself, locking you into the adobe jail.
