Can't create Animations in Firefox 71.0 64bit

[Feuerhase]

Hello,
for security reasons, at the first contact, I have answered the question if I want to receive information with "No".
Unfortunately I had to realize that I would have answered with "yes".

How and where can I change this in Firefox ?

Thanx
