foscam dvr and camera web plugins blocked by flash

In Firefox 52 (? I think) the flash execution is blocked by default.  There is no key present to disable the blocker in the Firefox config.  Instructions from Foscam support shows what to do go go round it.

If you are vulnerable to exploits this may allow malware to run flash exploits, so any PC this is installed on should be evaluated for public or even local exposure to malware.  Suggest no email, no browsing, limited lan exposure, or even private router natted if you are really paranoid.

****************
