The perfect add-on. Doesn't cause problems with my Firefox config, doesn't conflict with other add-ons, and is completely safe. That's due primarily to the developer's brilliant concept of building an add-on that cannot be installed and, in fact, may not exist. An extraordinary new software paradigm. Well-done!
