Welcome to the About Add-ons home page! This simple extension is designed to do only one thing: place an About Button on each extension, theme, and language in your Add-ons Manager.
About Add-ons was first released in early 2009 for Firefox, SeaMonkey, and Thunderbird. Sunbird support was also included shortly after, and finally in 2015, Pale Moon support was added.
Since About Addon's final release for Firefox and Thunderbird in May of 2016, Mozilla has abandoned its own technologies in favor of poor parody of Google's protocols (WebExtensions), leaving many developers, including this one, disillusioned with the direction the Mozilla is taking. In contrast, Pale Moon has stepped into place as an XUL-centric browser, keeping backward compatibility better than Mozilla's own flagship project. About Add-ons is now exclusively a Pale Moon extension.
About Add-ons is free for use or modification without limitation. However, it comes with no license, warranty, or guarantee of any kind. That being said, you can still ask any questions in the Comments section below, or contact me directly for assistance.
