Goofs

Character error 

The name of Grandpa's World War II squadron varies between the "Flying Hellfish" and the "Fighting Hellfish."

Continuity 

Ralph is in Bart's class in some episodes and Lisa's in others.
When Milhouse Van Houten first appears in The Simpsons: Simpsons Roasting on an Open Fire, he has black hair. In all subsequent episodes, he has blue hair.
The interior of the family's home changes from time to time, e.g. the size of the archway and what room it leads to.
Springfield Elementary School is yellow in some episodes and white in others, sometimes changing color multiple times in the same episode (later episodes corrected this continuity problem by making the school's official color yellow, and including a picture of the "old, white" school in Principal Skinner's office.)
When the older, male judge character is introduced in The Simpsons: Bart Gets Hit by a Car, he is referred to as Judge Moulton. In all other appearances and source books he is called Judge Snyder.
When wearing her normal green dress, Marge wears a red necklace. However, often she is shown for a single frame or two wearing a white one (generally this happens in close-up shots of her head.) This happens in numerous episodes.
The family portraits in the Hibbert home have yellow skin.
Chief Wiggum's proper hair color is blue. A common animation error is for it to be black in certain scenes (this generally happens in night scenes, or other scenes in dark places.)
Although the giant stone head in the Simpson basement is gray, in some episodes it has appeared rainbow-colored.
Some characters have brown skin in some episodes and yellow skin in others. Two examples would be Hans Moleman and Judge Snyder.
In the intro sequence, Lisa is playing a blue sax, but during the actual show she has a golden sax (this was corrected in the new HD intro).
When Moe appears in the first season he has black hair. In all subsequent seasons his hair is a grayish-blue.
In a few episodes, the twins, who are supposed to be sheet white, are yellow in brief scenes.

Incorrectly regarded as goofs 

... almost everything. This is a comedy animation series, and while efforts are certainly made to create a vaguely consistent setting in which mostly consistent characters live and work, the emphasis is clearly on laughs. Individual episodes must be consistent within themselves, but rigid continuity between episodes is unnecessary. Indeed, additional humor has been wrung, during the life of the show, from the very fact that the episodes are inconsistent with each other. Goofs based on "In one episode they say... but then in another episode they say..." are not being accepted.
When Waylon Smithers makes his first appearance in The Simpsons: Homer's Odyssey, he has orange skin. He has the standard yellow flesh in all subsequent appearances. This was actually a change that the creators made knowingly. Smithers was mistakenly animated with the wrong color and was made an African-American by Gyorgyi Peluce, the color stylist. David Silverman has claimed that Smithers was always intended to be "Mr Burns' white sycophant," and the staff thought it "would be a bad idea to have a black subservient character" and so switched him to his intended color for the next episode The Simpsons: There's No Disgrace Like Home_.
Fat Tony's real name changes from episode to episode, but this is probably intentionally because Mafia hit men are supposed to have many different names.
