Sorry, but it up to Norton to fix problems with their Firefox add-ons. If Norton needs help from Mozilla all they need to do is ask for it. But Mozilla can't take on the task of fixing another company's proprietary software - DMCA. https://en.wikipedia.org/wiki/Digital_Millennium_Copyright_Act

Symantec has struggled to get their Norton toolbar completed since before Firefox 41.0 as Norton was using a old way that was no longer supported. The change was known for months and Symantec even asked Mozilla to delay change for one Firefox Release to give them more time.
