I have reproduced this bug with Nightly 66.0a1 (2018-12-20) on ManjaroLinux 18.0.1, 64 Bit!

This bug's fix is verified with the latest Nightly!

But 2nd issue from [Additional Notes] is not fixed yet.

This issue is also verified as fixed on the latest Beta 65.0b7 (20181227144402) on Ubuntu platforms (18.04 x64 and 16.04 x32). For the other problem, mentioned on Additional notes, I’ve filled another bug (https://bugzilla.mozilla.org/show_bug.cgi?id=1516634) since it is related to the Fx 65 Cookie restriction feature and the regression range is different from the current issue.
