My Android phone isn’t my primary and does not have an active SIM in it (it’s WiFi only), but my Firefox has no ads, and blocks all the ads (that I’ve encountered at least). iOS… is iOS. I mainly use Safari there, but, that’s a whole other story. Suffice it to say, I don’t have this problem on either handset.
If you don’t disable it, they always have.
