FF Quantum 58.0.2
Elements not gone.
The FF update fixed the problem with outlook.com, so I am back to my non-beta version.
Both damned elements are back also.
I refreshed filters and made sure I only have the three you gave me.
I then disabled my addons and the We see you're using... is gone but the Upgrade to Premium is still present.
Wait!!! It took a few minutes, but both elements are back.
I re-enabled Privacy Badger and HTTPS Everywhere.
If I had to, I would rather disable them as a temporary solution, only.
