The EU’s Digital Markets Act (DMA) is reshaping mobile browser competition: Mozilla reports about six million extra mobile users chose Firefox via mandated browser-choice screens, with a 113% jump on iOS and 12% on Android and fivefold higher retention for those users. Differences in Apple and Google implementations influenced gains, and other alternative browsers also saw uplifts. Mozilla urges stronger enforcement and expansion of DMA-style choice to desktops and other jurisdictions like the UK, even as it joins coalitions warning against unrelated UK internet rules that could harm privacy, innovation and web developers. The story highlights regulatory leverage over default settings and platform behavior.
The DMA's mandated browser-choice screens show how regulation can rapidly shift user defaults and distribution for browsers, impacting product strategy and user acquisition. Tech professionals must monitor platform policy changes and enforcement as they can unlock or close user growth channels and affect cross-platform product planning.

Most newsworthy: Mozilla says roughly 6 million additional mobile users chose Firefox after the EU's Digital Markets Act (DMA) forced a browser choice screen on iOS and Android. What happened: under the DMA, first-time or post-reset mobile device setups present a mandated browser selection interface; Mozilla estimates that without that prompt many users would have defaulted to Safari or Chrome. Key players: Mozilla (Firefox), Apple (Safari/iOS), Google (Chrome/Android). Why it matters: the DMA's UX intervention is driving measurable shifts in browser market share on mobile, especially a 113% increase on Apple devices versus a 12% rise on Android, and highlights regulatory leverage over platform defaulting and potential calls to apply similar measures to desktop environments.
Mozilla reports that since the EU Digital Markets Act (DMA) obligations took effect, Firefox has been chosen via DMA browser choice screens more than six million times—about once every 10 seconds—with retention five times higher for users who select Firefox through the screens. Independent analysis found Firefox daily active users rose 113% in the EU on iOS and 12% on Android versus 43 non-EU countries after choice screens rolled out. Mobile gains are notable but desktop remains largely excluded, leaving roughly 310 million EU desktops without equivalent choice. Mozilla urges stronger enforcement as gatekeepers resist or weaken implementations; it argues privacy and security should not be used to undermine real competition and interoperability.
Mozilla says the EU's Digital Markets Act (DMA) has driven roughly 6 million users to choose Firefox instead of Safari or Chrome, with a 113% increase on iOS and a 12% rise on Android. The company credits differences in how Apple and Google implemented mandatory browser choice screens—iOS prompts users the first time they open Safari, while Android shows the screen on first boot or after a factory reset—for the disparity. Mozilla also reports user retention is five times higher than before the DMA. Other browser makers, including DuckDuckGo, Brave, Opera, Aloha and Vivaldi, have reported uplifts. Mozilla and DuckDuckGo are urging the UK to adopt DMA-style screens for browsers and search, and seek enforceable rules and annual prompts.
A coalition including Mozilla and the advocacy group Stop Killing Games has urged the UK government to abandon proposed internet regulations they say would harm users, developers and platforms. The groups argue the rules—aimed at online harms and platform accountability—risk overreach that could reduce privacy, stifle innovation, impose burdens on small developers and restrict gaming and web-based services. Key players are Mozilla and Stop Killing Games; the action involves public campaigning and policy submissions to UK regulators. This matters because the outcome could reshape content moderation, developer liability and technical design choices across browsers, web platforms and online services in one of the world’s major internet jurisdictions.
