Why has Firefox eliminated clearing history when firefox closes ?

Clearing history when Firefox closes is a security issue that should be kept as clearing history manually after every log in is unnecessary which is why it was part of firefox settings, I would really appreciate less bloatware and keeping what I always used in settings. Omitting clearing history when firefox closes is a breach of security not an added security. Thank you, P.S. Please consider changes carefully before you make them or you may wind up with more of what isn't wanted or needed and less of what is wanted and needed.
