From CNET: Mozilla just escalated an arms race with advertisers, releasing a new browser for iPhone and iPad users called Firefox Focus that blocks ads from tracking your activities on the web.
When you visit websites, many advertisers store text files on your PC or phone that are designed to show you ads you're more likely to click on. For example, you might check out a product on Amazon then see that same product advertised a later on a different website when web ad software sees you expressed interest.
Firefox Focus blocks that and also pares away traditional interface elements like menus and tabs to speed up browsing. It doesn't go as far as actually blocking ads, though, like Brave or Opera can -- and Google Chrome won't.
Mozilla's move underscores the tension between advertisers and people using the Web. Sites like Google search and Facebook social networking are free because of advertising -- but ads can invade privacy, slow performance, encroach on your monthly data-transfer limits and even deliver software that launches online attacks.
