I've installed
https://pi-hole.net/ on my Ubuntu box. Its a network ad blocker. Simply edit your DHCP server settings with the IP of Pi-Hole for your DNS servers. Boom, no more ads.
I've always been a supporter of online advertising until this year. I had some extremely offensive ads on Eurogamer, 2 infected ads on 2 different machines and battery sucking ads on my Android tablet.
With Pi-Hole, websites now load faster, I have better battery life and I can happily browse without all the click-bait nonsense at the bottom of every page.
There is a really nice and simply web interface to manage Pi-Hole. You can easily whitelist ads on your favourite sites or blacklist sites you want to block all together.
Overall it was well worth the 30-40 minutes to setup.
