Friction can make it easier to accelerate something or harder to. More friction on the object being accelerated means it is more difficult to accelerate it. You and a friend are pushing a heavy crate down a street from a standing start. It's difficult to accelerate it. Now try the same thing on a street that is covered with ice. (The two of you have spikes on your shoes.) Better acceleration.
