You can setup adblocking plugin on most browsers, that doesn't help with mobile devices
Another option which would give blocking to your wholehouse, including computers, phone, tablet, gamesystems, smarttv, ect. Is to setup a adblocking through your router or dns server. Routers: DDWrt/various, pfSense/pfBlocker, or dns server: rasberrypi/pihole. These take alittle time to setup though up and alittle technical skill. You can take it a step further and configure a VPN which amount other advantages would reroute your 3G/LTE traffic, back to your house giving you adblocking while away from home.
