• VISTA: C:\users\[User Name]\AppData\Roaming\Thunderbird\Profiles\xxxxxxxx.default
• XP / 2000: C:\Documents and Settings\[User Name]\Application Data\Thunderbird\Profiles\xxxxxxxx.default

2. Open the folder called “chrome”

3. Create a new file — (In xporer2: select F7 or right click an empty spot, and choose “new file”.)

4. Name it: userchrome.css

* To open and edit the userchrome.css file: double click.
