(Telecompaper) Yahoo has started a trial in the US that block access to people using adblockers, the Financial Times reported. Mail users in the US who employ adblockers will get a notic when they try to log on to their inboxes that reads: "Uh oh...We are unable to display Yahoo Mail. Please disable Ad Blocker to continue using Yahoo Mail." When asked about the trial, Yahoo said it was "continually developing and testing new product experiences" and would not comment on whether the company was considering a similar approach with its other properties, such as its digital magazines or apps such as Yahoo Weather.
