I do not think we will see them this year--the Julebukkers, I mean--not only because of the current pandemic conditions but also because the custom of Julebukking has pretty well died out.
Time was, though, when on winter nights around Christmas and New Years, the Julebuks, or Christmas fools as they often were called, roamed the countryside in search of food and fun. Jolly gangs comprising mainly young folks masked and disguised themselves in ridiculous get-ups--often in gender-bending fashion--and presented themselves in the doorways of their neighbors, singing and cracking jokes. This was a custom common in Nordic settlements.
