Here are some handy extensions to make your Tablet PC experience better on Firefox.
- GeckoTIP – Makes the Tablet PC Input Panel work in Windows XP Tablet PC Edition, also has an option for a left-handed scrollbar
- MenuX – Minimal Toolbar buttons designed with Tablet PCs and Laptops in mind
- Grab and Drag – scroll without scrollbars, it works like the hand in Photoshop and Adobe Reader, but it has physics added, allowing the page to scrolll a little bit or a lot based on your pen “flick”, it also has momentum and it slows down instead of stopping abruptly.
The next bunch are Gestures, which will do tasks based on how you move your mouse on your screen. You might give each one a try to see which one you like the best.
