I can no longer stream video from websites in firefox (v40.0.3), though they work with IE. Problem started abruptly last week. I am not aware of any changes, updates, or new software on my computer that may explain this issue. When I launch the video nothing happens and the cursor sort of flickers. How can I solve this? Thanks in advance for your help.

Shockwave Flash 18.0 r0 Shockwave Flash 14.0 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 18.0.0.232

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