I guess I am supposed to phrase this question like so: I was fired from my last job, should I allow a prospective employer to contact them?

Since I was fired from my last job, should I put down that whomever is looking at my job application can contact my former employer? I wasn’t in the best of circumstances at that job, and I am not sure that they could refrain themselves from repeating the garbage my supervisor would say about me. This is the third time I have tried to get this question posted, the title keeps it in need of being re-phrased, good lord.
