You should install uBlock Origin plugin for browsers. It will block any advertising and other unwanted content. I don't know how you guys living without an ad blocker.
I do use it on my PC, but I'm on my Android right now. Do ad blockers work on Android?
I guess I haven't cared enough to look since I mostly just do light web usage on my phone: HN, reddit, and twitter are about it, and ads aren't too bad on those sites.
Either way, I don't think it is too much to ask for web sites not to have actual scams on them. I'm not talking about legit ads which are annoying enough, but rather things that try to mimic a pop-up window and tell me my device is hacked or has viruses.
I'm not going to fall for that of course, but some people are less aware and might.
