The new Firefox will not work with my Amcrest Security cameras software. When I downgrade to the old version of Firefox, everything is OK. The next time I access Firefox, it automatically upgrades to the new version and Amcrest will not work

So with Firefox 55.0.3 the camera doesn't work. Which "old version" does it work with?

Before Firefox 52.0?

Hi   ! Your system details show that you have two versions of Shockwave Flash : 20.0 r0 and 26.0 r0 . This can cause problems, so please remove the oldest version.

Uninstall the Flash Player using that uninstaller.

Then re-install the latest version :
