I was browsing the other day the little extensions to my favourite browser, Firefox. On top on the favourites, there was a thing called Adblock. What would I need that I said to myself. I installed it anyways, and used it for the first time today.
IT IS AMAZING. Not because by just clicking on a ad, you can decide not to display the ad anymore, but because it redesigns the layout of the page taking ownership back of the spaces that used to be reserved for ads. No need to ask for a printer preview anymore. And configuration is super easy. A quick example is below.
Of course, it only runs on Firefox and Mozilla, not on MS has-been browsers.
