Thank you. Reloader 1.3.3 seems to help though still getting them (very briefly) between rounds. Also doesn't do much for every other aspect of HV. Stupid Mozilla... If this is due to the new quantum compositor us FF users are probably fucked.
As a short-term solution, you could delay dealing with Quantum Compositor/Firefox 53 code changes by using the Firefox Extended Support Release (ESR) branch. The current ESR should be running the 52.x branch at least until Q1 of 2018.
