I was using Chrome and doing the usual steps once a week kept ads away for a while but about a week ago it was no use.
We use a Mac for our main TV and were using Chrome, but it was taking up a ton of space and CPU so I just deleted it. I'm using Safari for now, All ads for the first time in a decade..
My secondary computer/bedroom TV is a crappy HP with the non upgradable RAM, I use edge and ads are still blocked with Ublock origin, for now
