Yeah, it's using upwards of 8gb of memory on my systems. It's ridiculous. Makes me wonder if they do any testing.
No excessive memory usage issues here. But I am using it with ublock origin. Ads seem to be the main culprit when it comes to excessive memory consumption from what I've seen. All in all, an excellent upgrade compared to previous iterations, and brings it up to par with Chrome and Edge. Edge is still a bit faster though, at least on my machine.
