I have not done any tests, but my reading of the code says that dom.enable_performance does not disable everything. Therefore, we should set dom.enable_performance_navigation_timing to false.

The same goes for dom.enable_performance_observer, although we may want a separate ticket for that one.

There is also performance.timeOrigin. See:

Based on reading the code, it appears to be rounded for reduced precision when privacy.resistFingerprinting = true. We will need to determine if that is sufficient and make sure the system time zone offset is not leaked by this feature.
