Hi, right click on the Firefox Desktop icon (or Program) > Properties > Compatibility tab.

Also note that you have 2 versions of Shockwave Flash - the oldest should be removed.

If your question is resolved by this or another answer, please take a minute to let us know. Thank you.

Shockwave Flash 19.0 r0 Shockwave Flash 15.0 r0
Having more than one version of a program may cause issues. You must remove the older programs. Then get the current full installer.

Note: Edge on Win10 does not use ActiveX version but its own Flash.

Flash: Grab the uninstaller from here: Uninstall Flash Player | Windows Uninstall Flash Player | Mac

Then reinstall the latest version.

Flash Player Version 19.0.0.226

Note: Windows users must download the “Internet Explorer” and “Plugin-based browsers” installers.

Adobe still offers Flash 18.0.0.255 as its extended support release further down
