1. Apple’s new iOS9, due this month, will include ad-blocking for the default Safari browser on iPhones (and, presumably, iPads). It looks like it will work similarly to the AdBlock extension for Chrome. I’m not opposed to ads — after all, my radio salary is dependent on them — but when advertisers abuse the privilege of access to my screen by using too many roll-over-pop-up ads, or video that auto-plays immediately, I want to banish them.
  2. A forthcoming upgrade to the Chrome browser will block websites from auto-playing video/audio while in a background tab. That includes YouTube pages or anything you’ve clicked on while working on something else but didn’t want to watch immediately. The browser upgrade will keep them quiet until you’re ready for them.
