I want to install firefox extension from my windows desktop application, how can I do that? For Chrome, I can add my extension id to registry, then Chrome prompts for enabling the extension when start next time. I wonder if there is similar way in firefox.

Thanks Herb

Download the full installer from; Download Firefox For All languages And Systems {web link}

If you don't want to use its default settings, use the manual option.

I think that would require to drop the XPI file in the extensions folder in the Firefox profile folder. You will have to edit the file name and make the first part the ID as defined in the manifest.json file (applications.gecko.id) like required with the other methods.
