Adblocking is one of the primary reasons I will always use the mobile site over the app. Why cede over navigation controls and privacy to an app when I can keep it all sandboxed in a familiar and (adblocked) place?
I've been using Chrome on Android, which is pretty much the experience you'd imagine (both pros and cons).
Firefox on Android supports extensions last time I used Android, and uBlock Origin works on mobile.
Can't remember when I've last seen an add on mobile and I use exactly that.
Firefox with uBlock Origin on a cheap ass Motorola phone with not very much memory.
