The Firefox Toolbar Tutorial has finally been updated with newer extension development practices. Here's a high-level list of what has changed:

• A few corrections and additions have been made to the Install Manifest portion of chapter 2
• One bug workaround has been removed from chapter 3, as it is no longer needed
• The information on useful development browser settings has been moved into chapter 4
• Several minor improvements have been made to the JavaScript created in chapter 6
• The packaging information in chapter 7 has been heavily modified, since JAR files are no longer required
• Minor updates and a new closing section has been added to chapter 8
