Make Firefox Pen-Friendly

It occurs to me, after my little exchange with Kevin Tofel about gestures in Firefox, that not everyone realizes how friendly the browser can be with the pen and tablet interface. Sure, there aren't any inking options, but for web surfing with a pen, Firefox can be tricked out pretty well with a few extensions.

• GeckoTIP: If you want to use the floating TIP, you need this extension, refined and maintained magnificently by Malorkus.
  
• All-in-One Gestures: Trick out the gestures however you want. Easily open and close tabs, switch from standard window to full screen, and navigate with intuitive movements.
• Grab and Drag: Scroll in any direction without reaching for the scrollbar. Great for long reading or trying to read overly wide pages.
