I use uBlock Origin (the full fat version in Firefox, not the lite version). It doesn't help, because the pop-ups aren't ads. There's one asking me if I wanna be spied on, one asking me to subscribe or sign in, and one huge one telling me that there's currently a discount on subscriptions.

I've got uBlock Origin on Firefox desktop too, and none of those show. Turn on more of the filter lists in the settings - especially the stuff in the "Cookie notices" and "Annoyances" sections.
