To use a Firefox theme, you need to apply it after installing. Firefox 3.x will automatically apply the installed theme for you. If you are using version 2.x, do the following:
- click Tools - Add-ons - Themes to open the Themes Manager
- select the installed theme
- click the Use Theme button
Now it's time to restart Firefox and enjoy your new toy...eh, theme. :)
To install a Firefox theme
offline, drag the downloaded JAR file on the Add-ons Manager window. Note: do NOT double-click the file! You will end up either getting error message or opening the archive.
