Can form history be activated manually?

The link above says form history is disabled:

Disable search and form history.

Before I bother installing LibreWolf, I would like to know whether the form history can be activated manually. I think it is very helpful and saves time.

It is stored only locally anyway, so it doesn't violate privacy like telemetry and add-on signing to. If my data was stolen, I would have much greater things to worry about anyway.
