Local Storage not saving

Question

Hello,I recently got a new laptop and when playing web games I've noticed that my data does not save when I exit. I've tried to change the settings via right clicking & going into Global Settings. On the 'Storage' tab, it is set to 'Allow sites to save ...' but I cannot change it. If I go into 'Local Storage Settings by Site', it is completely blank. When I add a site to the allowed list, its as if I did absolutely nothing. The list stays blank after I 'add' to it. I have since discovered that if I go to the Updates tab and click the 'Change Update Settings' and allow in the User Account Control popup, I can change the previously unchangable settings. And sites now appear in the storage list that used to be blank. But once I close the little window for Global Settings it all goes back to the way it was.I'm using Firefox 64.0.2 on Windows 10 with shockwave flash version 32.0.0114 (NPAPI)Here is a link to a game that does not save anything once I close the tab. https://www.kongregate.com/games/Juppiomenz/bit-heroes  For example, if you go into the 'Settings' menu (little gear near the bottom right) you can mute the music. It should remember that next time you load the page, but it doesn't. At least, not for me. Thanks-DG
