This was requested by Duck, so I thought I'd post it here, in case any one else cares. All of these are available from the Firefox extensions site.

There are a couple more that should be included on this list, but they're installed on my home computer and not the one at work where I am now.

• Tabbrowser Preferences - Gives added control to tabbed browsing
• Open Source in Tab - Keeps me from having too many windows open.
• PageStyle2Tab - It just looks cool.
• TabFX - More enhancements to tabbed browsing.
• Right-Click-Link - For the link that isn't a link.
• Extended Statusbar - Useful at times. Works like Opera's.
• SessionSaver .2 - "Magically restores your last browsing session."
• PDF Download - Because Acrobat doesn't always agree with Firefox.
