I have tried to test this report on Ubuntu 16.04 x64 using the latest Nightly and Fx release builds. However, I'm not able to install 'bumblebee' and also my desktop is using Intel HD Graphics 630. In order to involve the development team and based on other similar reports, I will move it to Core:Graphics.

Tested with `primusrun` . Seems to run fine.

This is pretty weird that FF seems to run smoother and faster ( observable when there's overall high memory usage ) WITHOUT GPU acceleration i.e. without primusrun.

A false positive there. Upon comparably long term use I can assert that it runs way better with hardware acceleration. 
Seems more of a optirun issue.

Fix: Run with primusrun.
