Midori

Summary

Since some time I'm a proud user of Midori because it is much faster than firefox and also faster at starting than chromium. Unfortunately there are some bugs but hey it's a beta.

Main

Something I really like is the adaptability using javascript and css.

Scripts I'm using are:

BlockFlash2
blocking google ads1
blocking google ads2

Because I'm a vim user I also have changed the bunch of shortcuts of midori to suit my wishes and I'm using this script for navigation:

Arch Linux Forum Post - VimNav

old Vim-like

old Vim-like

vimkeybinding

Then a friend and I, we've improved this keynav-script.
We've changed the binding and added code to deny execution while an input or textarea field has focus.

// Then restart Firefox and revisit this script.

/*
 
@what
 
The script enables keyboard navigation.
 
@how
 
Pressing a hotkey displays a (or hides the) label near each clickable element.
Pressing the shortcut triggers the "click" for the associated element.
 
@structure
 
- A Map object: enables mapping of a String (the shortcut) to an Object (the DOM element).
- A Configuration object: contains anything that can be "externalized" (preferences, actual label generation, etc).
- A KeyNav object: the main object that handles all the messy stuff.
 
@changelog
 
0.1
	initial
 
0.1.1
	- added labels index for faster looking up of labels
	- moved creation of labels to initialization
	- added event handler for invalidating labels when document changes
