As of the November 6, 2017 update, websites do not display properly in FF 56.0.2 (Windows 7). If I disable ABP and refresh the page, everything is fine, but if I re-enable ABP, all the browser tabs immediately go blank. I can view the source, so the pages were obviously downloaded properly, but they just aren't being rendered at all.

Everything was fine the morning of November 6; the problem started sometime in the afternoon.

Please fix ASAP.
