We're doing UI memory leak testing of webadmin across browsers. The tests use selenium [http://www.seleniumhq.org/] which drives the browser to do hundreds of repetitive actions, which then over time exposes browser memory leaks in the actions being performed.

X = repetitions (over time)

Y = memory consumed in MB

The graph shows that, as the number of repetitions through the application increases, Firefox Quantum 57 leaks less (lower slope) than Chrome 62 (latest) and older Firefox 52 ESR. Also, it uses less memory the entire time (lower on the graph). [FF 57 is also just plain faster per repetition, but I haven't posted that graph here. Take my word for it :)]
