Plugins

This is the homepage of the Mozilla Plugins project, where we've collected hyperlinks to resources for plugin developers.

NOTE: Some of the links on this page points to devedge.netscape.com which was recently taken offline by AOL. We're working on getting our hands on the content that was hosted on that site so that we can host it ourselves and link to it again. There is no current ETA for us getting the content, but we don't expect too much of a delay any more. For now, web.archive.org rescued us.
