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 (1659988) as well as 1643200, which is the first place I landed in LaunchPad.
