Hi, I check my storage for large folders and I came across folder inside Firefox profile called "cert-revocations" and its size is more than 400MB, can I delete it safely? What cons of deleting this folder? and why Firefox doesn't clean this folder periodically?

No, you shouldn't remove this folder in settings/security-state/cert-revocations. It is part of a new way for handling certificate revocations to replace OCSP called CRLite that uses filters to compress revocations and store them locally to overcome issues where OCSP fails or takes more time.

Thanks for your reply, But the folder is large and grow over time! Why Firefox doesn't clean it periodically? What the negative side effects of deleting it?

You can try to clear the cert-revocations folder to see when Firefox repopulates this folder as this folder is in the secondary location used for temp files like the disk cache and the thumbnail cache. The main CRLite data might be in the security-state folder in the main profile location.
