Steps to reproduce:

Firefox/66.04 64bit Windows 7 (also at least in previous 66.03)

Press Ctr+Shift+Del

The options for clear history appear, > tick all options, > choose eg 'Last hour' or 'Everyting' > click 'Clear Now' button.

Actual results:

Nothing?: in 'Options/Privacy & Security/Cookies and Site Data/Manage Data' I see that cookies are still there; if I click the 'Remove all' button in this window, then the cookies are deleted.
(Since the little window 'Clear Recent History' appears etc, I used to think it was working until I saw cokies remained [even after ticking to block all cookies and having closed the pages that set the said cookies).
but

I wonder if Ctr+Shift+Del isn't deleting anything at all besides cookies.

Expected results:

All cleared, including cookies.

Does this reproduce in a clean profile and/or on the latest Firefox Nightly? If so, can you please use mozregression to find a regression range?

Can't reproduce and no reply from the reporter. Closing.
