Just a place for me to keep track of comparative memory usage over time. Screenshot before/after [reference benchmark](https://github.com/gorhill/uBlock/wiki/Reference-benchmark). Great care taken to ensure memory was garbage collected before screenshots taken. To force memory garbage collection, browser left on idle for more than 1 minute, then dev console of each extension opened, _Timeline_ tab, then clicked twice on the trash can icon.
