Set Backspace Key to Go Back To Previous Page

Set “browser.backspace_action” to 0.

• 0 ⇒ ⌫ Backspace = goto previous visited site/page.
• 1 ⇒ ⌫ Backspace = scroll up a page, and 【⇧ Shift+⌫ Backspace】 = scroll down.
• 2 ⇒ Don't do anything special. (default on Linux Firefox)

Turn on AutoScroll in Firefox Linux

To turn on autoscroll feature on Linux:

• Double click to set general.autoScroll to true

This lets you middle-click on a empty area to pan-scroll in any direction by moving mouse.

Set Accelerated Mouse Wheel Scroll Speed

• set mousewheel.acceleration.start to 2. (default is -1)
• set mousewheel.acceleration.factor to 30. (default is 10)

The change is immediate. You don't need to restart Firefox. This works in Linux too.
