Thanks, this is super helpful. I do have to agree with the spamminess of the Pocket-sponsored ads on new tabs. Last time I used FF I didn't mind the Pocket stories section, but when I opened up today it was half-full of credit card offers and other undeniable spam (unlike sponsored news stories that I remember from before).

I get that they're trying to free themselves from utter dependence on Google search revenue, but boy is this a spammy alternative... I used to leave the Pocket stories on, but now I will definitely be disabling them.
