Firefox Extension Clean-up Round-up

I had way too many extensions vying for space on my status bar so I'm going to uninstall some and disable a few more.

Uninstalled Extensions:

• Google Calendar Notifier - works fine, but I never use it. It's the extension that started this cleansing.
• Download Statusbar - yet another addition to my status bar extension. It was actually disabled, but it's time for it to go.
  

Disabled Extensions:

• Greasemonkey - never really got used... but I'm not ready to drop it entirely.
• IE View - I recently added IE Tab... which works quite well.
• View Source Chart - never used.
• Firebug - I know it's popular, but I never got into it.
