That is unfortunate! It is crucial to pick yourself up quickly and start applying for other freelance jobs. Many freelance platforms allow you to showcase your portfolio, which therefore enables you to access job proposals and gives you enhanced outreach.
Only when you are asked to discuss your dismissal should you explain the circumstances. However, it is an unlikely question for an interviewer to bring up as your previous employer should not disclose this.
At your next interview have confidence in yourself and your skillset. Give the interviewer what they are looking for in terms of knowledge and provide evidence that you are well suited to their niche.
