Repeating post from bug #1659988 Thomas,
I believe I was already on FF 51.0.1, but after my Session Manager addon updated to 0.8.1.13, I began having the issue where everything from the Internet would display as black and white rectangles. I believe this happened immediately, but I can't be sure as I was chasing a separate problem at the time with gmail servers that appears to be a DNS issue (very long traceroute times). I applied the patch as you described for usr.bin.firefox_patched in post #21, and FF began working again. Thanks for the work you put into the patch! Reporting the patch is a fix for this bug (1643200) Using: Trusty System76 gazp9 laptop FF 51.0.1 Session Manager 0.8.1.13 Thomas, as you suggested in 1659988, the Session Manager addon added multiprocess support, i.e. E10s, in the latest version. Apparently, that was the last thing blocking E10s from being enabled, and once it was, I experienced this bug. Hopefully, someone will post here when this is resolved and the patch you wrote can be removed.

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 libfcitx-gclient0 1:4.2.9.1-1ubuntu1.16.04.1 libfcitx-utils0 1:4.2.9.1-1ubuntu1.16.04.1 libprocps4 2:3.3.10-4ubuntu2.2 linux-firmware 1.157.5 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.
