The second link offers a solution:
To provide this fix on short notice, we are using the Studies
system. This system is enabled by default, and no action is
needed unless Studies have been disabled. Firefox users can
check if they have Studies enabled by going to:
Firefox Options/Preferences -> Privacy & Security -> Allow
Firefox to install and run studies (scroll down to find the
setting)
This can't be done on my FF - it's greyed out and cannot be enabled.
