I am writing this guide since Midori is the default browser in Slitaz 3. Your first thought may be to install Firefox and not giving Midori a try because it lacks features. I thought it lacked features or Addon's also until I dug around some. If you want to know the history of Midori visit it's Wiki page: Midori Wiki

Things that I will cover:

Ad Blocking
Custom Search Engines
Flash Blocking
UserSripts

Well had this written up and half of it became a run on paragraph and I have no idea why. I will fix it and get it back up I guess.
