It&#x27;s nearly 2016 and Firefox can still only using 1 of my 8 CPU cores, and I can still bog down the UI with heavy web apps. My favorite email client is no longer supported, and now a potentially great privacy tool is being dropped. Meanwhile, after wasting countless man hours on a Mobile OS, they&#x27;re now &quot;pivoting&quot; to IoT.<p>Why can&#x27;t they just focus on what people value them for, web browsers and privacy?
