It's easier to deal with than you think. Don't outright admit to a firing when the question comes up. I'm not saying make something up on the fly, because they'll smell the bullshit, but think of how you can spin your termination in a positive light. Leaving because a project was completed/cancelled or company priorities changed is generally seen positively, even if the truth is you were fired from one of those jobs for being incompatible with the rigors of the role.

If you're just coming out of a firing, the worst thing you can do is have a mea culpa moment of clarity when you're negotiating for your bottom line. You'll get the old standard, "thanks for your time", and away they go to the next person, who may have also been fired, but bent the truth in their favor to get the job.
