One thing I've noticed is that for years uBlock used to say 7% of all data requests was blocked; in this past year it's climbed to 8%. So almost 10% of data transferred is useless to me as it consists of ads, trackers and annoyances.

I wonder in my lifetime how much bandwidth and energy I've saved if a blocker has blocked around 10% of all data requests.

I'll stick with the full version on Firefox.
