Adobe Flash Player Problems with Firefox 65.0

Hi,

I use Firefox and Adobe Flash to play several internet games. Today, one of my laptops (W7Home-64 bit) updated to FF 65.0 and then would no longer play games like Tankionline.com and other Flash games on armorgames.com. I tried System Restore, which worked until the next time I closed and reopened the browser which then automatically updated to 65.0. I played around with it, even copying the Profile directory from another computer, removing/reinstalling both FF and Flash, did not work. Game works fine with MS Internet Explorer. Other laptop and desktop also worked fine. Then, I accidentally closed my browser on my desktop (W7Pro-64) and then when reopened it also automatically updated to 65.0. It now exhibits the same problem, Flash games will not work.

The flash player is launched by FF, but flash games just hang and will not play. Flash is version 32.0 r0, the latest available.

I have a 2nd Laptop that has not yet updated to 65.0 and I have disabled the auto updater while waiting on seeing if the problem can be resolved.

Thank you for any suggestions, Tony D.

If you have the latest Flash already:

Feb 12th, 2019...
A New Flash Update (32.0.0.142). Go check at:
https://get.adobe.com/flashplayer
or Go to Add-ons > Plug-ins > Shockwave Flash - Options in the FireFox Browser.

FireFox Sandbox Issue. Needs to be disabled.
Disabling the sandbox requires using about:config to set...

dom.ipc.plugins.sandbox-level.flash

...to 0 and then restarting the browser.

The sandbox is known to prevent the following features from working:

  • Print to PDF from the Flash print dialog
  • Print to “Open in Preview” from the Flash print dialog
  • Quicklook in the File->Open dialog
  • Saving files to the filesystem from a Flash applet
  • Flash applets downloading and running the Adobe Air installer
  • Flash triggering Adobe Air applications to run

In the Address/URL box of FireFox, type in About:Config. Once there, enter in the Config Search Box:

dom.ipc.plugins.sandbox-level.flash

...Double-Click on this and set the value to 0. Quite FireFox and Restart it. Done. The above problem(s) (games, too) should now work.
