How to enable npapi plugins which are placed in "page-worker" page of Firefox extension?

Hi all,

Since Firefox 26 has decided to set "click to play" plugin by default, I have encountered a enabling plugin problem.

If the plugin is placed in the web page, either visible plugin or invisible plugin has a chance to enable it while navigating to that web page.

However, in my case, my plugin is placed in the extension's "sdk/page-worker" page, so there is no chance for the user to enable it unless I open the "page-worker" page(resource://...) purposely.

I think it will not be a good solution to open extension's page to let the user activate plugin.

Is there any good solution for my situation?

Thanks.

Powen
