Google, Microsoft, and Meta largely ignore cookie opt-outs, independent audit says
Bottom line: Those annoying cookie-consent banners that have flooded the internet over the past several years are supposed to give users the option to block most tracking cookies from advertisers. However, a recent California audit claims that the largest ad tech companies usually send cookies anyway, having decided that simply paying potential billions in fines is more profitable.
Why it matters: More than a decade ago, Europe rewrote internet rules which effectively forced the entire internet to adopt stricter rules on cookie consent by amending the ePrivacy Directive. Since 2009, from big tech giants, to small personal blogs, and virtually any internet-based organization had to display a "cookie banner" to first-time visitors. Collectively, European users spend an estimated 575 hours every year clicking through those pesky prompts.
Firefox now blocks third-party cookies when enhanced tracking is set to Strict mode. Firefox 132 also introduces 4K video playback for streaming services via Microsoft PlayReady, reducing battery drain and enhancing performance when watching movies.
