In a previous post I wrote about the increasing intrusiveness of ads on web pages and the imperative for using Reader View or an iPhone ad blocker in Safari. I suggested 1Blocker (free, $2.99 for Pro version). Now a new option is available from Mozilla. Focus by Firefox (free) is an open source app that blocks unwanted content and tracking when you're accessing web pages via Safari. This improves performance and protects your privacy.
