Unlike Chrome and Edge, Firefox does not ask for the permissions that Artstation Plus needs during installation. Firefox incorrectly labels the permissions that addon needs as "Optional permissions for added functionality". However, these permissions must be granted or Artstation Plus will not work. Open Extension, select «Artstation Plus», then «Permissions» and turn on «Access your data for sites in *artstation com domain».
