There are three ways to edit your Mozilla Suite, Firefox or Thunderbird configuration:
- Do (much of) it through about:config. In Thunderbird 1.0.x, use AboutConfig extension.
- Use the ChromEdit extension (version 0.1.1.1 is not compatible with Thunderbird 1.0.2).
- Learn how to do it manually:
- Firefox
- Thunderbird
