I’ve been getting quite a few messages about how to get a theme to activate. I think that Mozilla has a usability issue as once a theme is installed, nothing happens. This tends to confuse quite a few people who are new to themes. So I thought I’d put together a quick ‘Now What?’ post.

After you’ve installed a Firefox theme, follow these 4 steps:

  1. Go to Tools -> Addons.
  2. Click on the Themes tab.
  3. Click Use Theme on the theme you’d like to use.
  4. Restart Firefox.

Activate Theme

Make sure you close ALL Firefox windows when restarting Firefox. When the browser restarts it’ll be using it’s nice new theme.

To revert back to the default, in step 3, select Firefox (default).
