I've relied on Ghostery for years to give me granular control over trackers. As an online seller, I need to enable certain trackers on certain sites only, so the global blocking offered by other privacy managers doesn't work for me. HOWEVER, I'm having issues with the add-on for Firefox on Android (Nougat on phone; have settings in Lollipop on tablet). It shows me bunches of trackers, some of which are definitely nonessential and are flagged as slowing down the browser, but there is no ghost icon and noplace to access settings so I can block trackers by class or block/trust individually the way I can on my desktop. In addition, I keep getting a Firefox popup on my phone saying that Ghostery's script is unresponsive. So 5 stars for desktop but not so many for phone.
