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

I suppose this is a restartless extension?
For that we have this bug open: https://bugzilla.mozilla.org/show_bug.cgi?id=989967
For non-restartless extensions you can bundle plugins and have them automatically activated already:
https://bugzilla.mozilla.org/show_bug.cgi?id=982101

There was some relevant discussion here:
https://bugzilla.mozilla.org/show_bug.cgi?id=931705

I don’t have experience with the addons SDK , so i’d suggest to ask on dev-extensions for further questions on the missing chrome privileges problem:
