Friction force opposes the Relative Motion between the Contact Surfaces.
For Example, when you walk, Friction force is acting in the forward direction because it opposes the motion of Foot relative to ground ( Which is backward) .
Approve if i helped :)

most of the times it acts opposite to the direction of "relative motion" but not always
plz approve if it helped :)
