Mozilla has no control over 3rd party programs such as add-ons and plugins.

You would have to contact FVD support.

I'm posting this Privacy Policy by Nimbus, maker of FVD, to help other forum readers who share my concern. Although I found it in an Opera add-ons webpage, the information is not browser-specific.

To Pkshadow: if I had posted my contact info I'd be broadcasting the free download of my intellectual property in Vimeo.

My NPAPI Plug-in was up-to-date, but, you're right, I had an outdated PPAPI Plug-in that I don't need. Thank you for the heads-up. I've removed it.

I assumed, perhaps incorrectly, that the FVD add-on in Firefox was a consensual, even licensed, arrangement between NimbusWeb and Mozilla's Firefox. That is why I posted the problem here as a start.

Thank you for listing NimbusWeb's general support contact info. But I'm happy to report that my outreach to NimbusWeb's legal@everhelper.me, as specified in their Privacy Policy that I posted above, generated a rapid and cooperative response. They're going to add my Vimeo URLs as exceptions to their next FVD update.

To FredMcD, thanks for suggesting that I contact FVD in the first place. That set me on the path to my solution.

Although this may not have been Mozilla's problem to solve, the fix now lives in the web for others like me, an independent artist, who suddenly has to scramble to protect their intellectual property.

I consider this problem solved.

A suggestion: If you need to send 'private' information, send it using Private Mail on a forum, or an e-mail.

I am glad to hear that your problem has been resolved. If you haven't already, please select the answer that solves the problem. This will help other users with similar problems find the solution more easily.

Thank you for contacting Mozilla Support.
