Operating System

Windows 10 (Build 19045.2965)

Additional context

Using Latest version of Docker and Portainer.
I remember similar issues months ago, so could be present in prior versions of Firefox as well.
I tested with MS Edge, and it worked correctly.
Tested with Firefox Mobile (version 113.1.0, Build #2015950739, Android), and it worked correctly.
