I've used an iPad and iphone for the past several years to access Tidefans, but I've just started using an Apple Macbook. Now I've got ads to the left of me.....ads to the right of me.....and video ads popping up too. I can't scroll the forum without a big huge intrusive advertisement after every 5th topic. why didn't this happen on my handheld devices, but now happening everywhere on my laptop? Please help an old man understand how to combat this intrusion!!!
