Use an ad blocker that DOESN'T compromise on your privacy (Adblock plus). It's light weight in resources and has all the tools you'll need, like white listings and a library of blocked malicious websites. Compatible for Chrome and Firefox.
I prefer it for myself, however it has a tendency to block a little to much causing annoying pop ups, which is primarily why I still install ABP for customer computers.
Thanks for the tip. The only reason why I installed ABP was to block YouTube ads. They would serve me 2 minutes unskippable ads for a video just as long. Had I known uBlock was FOSS I would've tried it sooner. Currently use it on FF on Android. Like it so far.
