Rated 5 out of 5 stars

What a beautiful little application! Install it, then click on Tools (on the Mac) and Infolister is on the menu. Pop it up and see a list of all your Firefox themes, extensions and plugins, including their Enabled/Disabled status. Plus, the names are links. Click, and jump to the developer's page. Make a copy of the list, and have the ability to restore your Firefox customizations even after a reinstall! Beautiful work, Nickolay! Functional, elegant, and useful.
