Benchmarking Mozilla's Firefox Performance Over The Past Two Years

Basemark was another example of the performance getting slower with time, particularly since Firefox 61.

The JetStream performance took a sizable hit from Firefox 59 to 60 and has yet to recover.

CanvasMark took a particularly big hit with the transition to Firefox 62 but at least this HTML5 canvas benchmark should improve once WebRender rolls out by default to Linux users.

MotionMark meanwhile has been a bit bumpier ride between Firefox releases but still Firefox 71 nor the alpha/beta releases are near the peak performance seen around Firefox 64~65.
