Flash failed on Firefox Quantum 58.0.1 (64-bit)

ronbar59

Until today 2/7/2018, I have been able to view content which needed Flash on Firefox Quantum 58.0.1 (64-bit) when using my Windows 7 64-bit laptop. Today Firefox is telling me that Flash is not installed. When I download and try to install Flash, I get a message that "Installation of Flash failed." What can be done to fix this problem?

Try reinstalling Flash by downloading and running the installer from here: https://get.adobe.com/flashplayer/

Make sure it is enabled under about:plugins <<

If this solved your problem, please mark as solution. Thank you!
