I will absolutely take the Pocket integration in Firefox over ad-banners any day of the week. I've used browsers with ad banners in the past, and this is infinitely better.

I see three links (on mobile) of actual content; articles or blogs with substance that I may or may not find interesting. They fall below the list of my most visited sites, and they're eminently missable. Depending on how I open Firefox I will not even see them due to bypassing the start page.

I've read several of those articles and found them interesting. It's value added to me, and I don't have to see ad banners for stupid crap in the bargain.

I don't see the problem.
