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.
libfcitx-gclient0 1:4.2.9.
libfcitx-utils0 1:4.2.9.
libprocps4 2:3.3.10-4ubuntu2.2
linux-firmware 1.157.5
procps 2:3.3.10-4ubuntu2.2

unattended-
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.

I tried to disable and enable hardware acceleration in preferences and restart firefox, but that did not improve anything.
I figured out that I had
layers. acceleration. force-enabled= true
in about:config tab.
For instance, I've set
layers. acceleration. force-enabled= false
After that, instead of getting black tabs I now get white tabs. The funny thing is, that I can click on invisible elements of the web page, so it is loaded but just not visible.
When I click on invisible elements of the web page it even "opens" the corresponding URL. Just that it is not visible again.
I guess this issue has to do something with graphics acceleration. Or maybe e10s if something changed there.
