I do not use a smart phone or a tablet, only a laptop computer. At the advice of someone here on another thread (and thanks to them) I installed DuckDuckGo.com as my primary search engine (instead of using Google, though I still use their maps). Not only does this search engine not track your usage, it also has a built-in ad blocker that works on all sites, not just ones you find using their searches. So I have no pop-up ads on CanonRumors or elsewhere and I would recommend installing either this or another ad-blocker. However, forgive my ignorance, but I don't know if you can install those on a tablet like you can on a computer.
