One of the reasons I use Mozilla Firefox is its huge universe of extensions, scripts, styles, and other add-ons which can make it behave the way you want it to. I've customized my Firefox installation pretty extensively.

This list is current as of Firefox 21.0.

Android

Using Roboto instead of Open Sans

  1. Go to about:config
  2. Set to "Roboto"
    • font.name.sans-serif.x-unicode
    • font.name.sans-serif.x-user-def
    • font.name.sans-serif.x-western

Font size adjustments

  1. Go to about:config
  2. Set font.minimum-size.x-unicode and font.minimum-size.x-western to 14
  3. Set font.size.inflation.minTwips to "140"

Enabling off-main-thread compositing

How to help testing off-main-thread compositing from the Mozilla Gfx Team Blog describes everything that needs to be done. In short:

Set to true:

and into ~/.bash_profile (warning: this will cause all Firefox, including stable versions, to use OMTC):

export MOZ_USE_OMTC=1

You can also set:

to display a pink FPS counter in the top left corner. If you see the counter, than OMTC and layer acceleration are working.

722012 – [Meta] Implement OMTC on Linux tracks whether OMTC has been enabled on Linux.

Fiddling

To tinker w/ browser styles/events/etc, navigate to chrome://browser/content/browser.xul and launch the built-in developer tools.
