Any general purpose NPAPI plugin to invoke external download tools?

I am looking for a general purpose NPAPI plugin that can used to invoke GetRight/FlashGet/OrbitDownloader/I开发者_开发技巧nternetDownloadManager/etc.

Has anyone written that already? It's like FlashGot for NPAPI browsers.

NPAPI plugins are for embedding alternative content into a page, not for generally extending the browser with new functionality.

What you are looking for are extension or addons (sadly and confusingly also sometimes called plugins) and those are mostly browser-specific - search first before writing your own.
