Is it possible to stop NPAPI plugins from starting with Firefox? I currently have Pipelight installed to use Silverlight in my normal Firefox installation. However when I use the High Security Mode it always tries to install Silverlight in the new user account. The installation seems to fail, causing the Pipelight installation wizard to stay open. Thus I always have to close the firejail process to get rid of the window, which is kind of annoying.

On another note, the same happened by just calling firejail firefox before I added the following items to my whitelist.
whitelist ~/.wine-pipelight whitelist ~/.wine-pipelight64 whitelist ~/.config/pipelight-widevine whitelist /etc/pipelight-widevine whitelist ~/.config/pipelight-silverlight5.1 whitelist /etc/pipelight-silverlight5.1
