600K in a month sounds about right. I have an install that’s above 13 million, which is a little over 1 year of daily usage.
I also insta-install it when I see an ad and then remove it if it’s not my device. The modern internet is shockingly bad without adblocking.
Seconded. uBlock origin is ridiculously powerful and configurable. It can DRAMATICALLY speed up site loading while only occasionally breaking functionality. Typically if the site is entirely JavaScript rendered like reddit.
