EdgeWare от PaulJayD

The EdgeWare Firefox extension advances browsing by creating an ergonomically superior environment which is physically fast and easy to use, whereby the entire left margin of the Firefox viewport (the area which displays web content) becomes a clickable "field" which can be utilized without looking.

The EdgeWare Actions provide single-, double-, long-, and serial-click support, along
with wheel scroll support, and can easily be customized via simple drag & drop selections.

Available Actions allow you to quickly and easily perform the following functions with
minimal hand-eye coordination:

* Audio Mute All
* Audio Mute All But Current
* Audio Mute Toggle for Current Tab
* Load previous page in current Tab (Browser 'Back' button)
* Load next page in current Tab (Browser 'Forward' button)
