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
, and Thunderbird
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. So, for now, About Add-ons may be considered a Pale Moon and SeaMonkey extension that still supports older versions of Firefox and Thunderbird.
