||The PDF plugin allows Chromium users to view PDF files directly in Chromium. The PDF plugin is not officially supported for Chromium by upstream. It is released for Chrome and updated silently, and we are not allowed to mirror it. Debian provides a versioned plugin that matches a specific Chromium revision which we use. The revision of the plugin changes when Debian changes their Chromium packages, which means the fetch of the plugin will fail. The users of the pdf plugin will have to update this exheres to match the revision when that happens.
