EMPLOYEE0Sorry to hear you're uninstalling. If you're tired of this theme, you can find other themes at our download site www.thunderthemes.com or all our themes are at brandthunder.com/gallery.
To Uninstall, depends on the browser you're using.
In Firefox, you can go to menu bar and select Tools --> Add-ons --> then either Extensions or Themes. I can't be more specific without know which theme and which version of Firefox you're using.
In Internet Explorer, you'll need to go to Add/Remove programs in the Control Panel, then select the theme on your machine to uninstall.
Good luck and thanks for trying Brand Thunder's browser themes.
