Firefox Theme and Extensions

One thing I really like about Firefox is that I can run it both on my Windows and Mac machines using the same extensions, themes and bookmarks. Below is the theme I use for Firefox and the extensions I use in case you haven't seen these yet: Theme

• Charamel

Extensions

• Tabbrowser Preferences
• TinyUrl Creator
• Copy Plain Text
• IE View
• Web Developer
• BlogThis

Do you use any that I'm not? If so, please share!
