@blantonradford Thanks for reporting back.
That can easily happen: As documented in my previous comments, I had
black/white tabs already with FF 50. Most users won't have noticed that
because the extension "ubuntu modifications" is installed by default and
mitigates this problem for versions _before_ FF51 (or FF51.0.1).
However, starting from FF51.0.1 (at least), that extension does not help
any more and the issue gets exposed to users.
Technically, you hit this issue as soon as E10S gets enabled, be it via
update or updating previously E10S-incompatible extensions (like Session
Manager) which then become compatible to E10S and therefore allow FF to
enable E10S.

Title:
After updating to firefox 50.0, tab goes black instead of showing web
pages
Status in Mozilla Firefox:
Confirmed
Status in firefox package in Ubuntu:
Confirmed
Bug description:
Today, I updated firefox to version 50.0. This update was offered to
me via the official updates I got for ubuntu 16.04.
After restarting firefox, I get a black tab content when I "open" a
web page. For demonstration, see the screen shot attached.
Note that I still can edit preferences or "about:config". Tabs only go
black for web pages.
I get the black tabs after installing firefox together with this set of
updates:
isc-dhcp-client 4.3.3-5ubuntu12.4
isc-dhcp-common 4.3.3-5ubuntu12.4
libfcitx-config4 1:4.2.9.1-1ubuntu1.16.04.1

procps 2:3.3.10-4ubuntu2.2
python3-distupgrade 1:16.04.18
ubuntu-release-upgrader-core 1:16.04.18
ubuntu-release-upgrader-gtk 1:16.04.18
unattended-upgrades 0.90ubuntu0.2
xserver-common 2:1.18.4-0ubuntu0.2
xserver-xorg-core 2:1.18.4-0ubuntu0.2
Please not that xserver got updated, too.
The behaviour also remains after a reboot.
Other applications, including Thunderbird, do not show similar
behaviour.
