Hello, My apologies if this has come up on the list or there is already an extant answer elsewhere (or if the question doesn't apply, which might be the case).
I am not sure how to describe Pocket, but it is advertising that is prominently featured in the "New Tabs" page. The configuration setting is also prominently featured in the settings page which it is located. I would like to know if there is any recourse. I have disabled it, but it is still present in the menus. It looks like it generates a unique advertising ID, which I have cleared in "about:config." Cheers, R0b0t1
