Firefox on iOS gains built-in ad blocking from Mozilla

Mozilla is officially launching a built-in ad blocker for Firefox on iOS, using Apple’s WebKit Content Blocker and the EasyList filter to block most third‑party ads and trackers before they load. It’s disabled by default and can be toggled in Firefox’s settings (Settings > Browsing > Ad Blocker) or during a session from the site menu. Not all ads will be blocked—ads served directly by sites, search results, and sponsored content in new tabs can still appear—making this the first iOS ad blocker for Firefox while rivals like Brave, Vivaldi, and Opera already offer similar features.

Mozilla-Backed Report Alleges Windows Nudges Toward Edge

A Mozilla-commissioned study, Over The Edge 2.0, accuses Microsoft of using design tricks in Windows—such as banner prompts, a pre-pinned Edge, and preselected Copilot data-sharing toggles—to nudge users toward Edge. The report finds regional differences (EEA vs US/UK/India) and notes changes in the EU, but Edge’s overall market share remains modest while rival browsers grow. Regulators and competitors call for fair competition; Microsoft did not immediately respond to requests for comment.

Period trackers under the privacy microscope: who guards your data

Period trackers under the privacy microscope: who guards your data

Mozilla’s investigation of six popular period-tracking apps finds a spectrum of privacy practices: some apps keep data on-device with minimal sharing (notably Euki), while others send health details to third parties (Stardust to RudderStack; Planned Parenthood’s Spot On via AB Tasty; Flo/Clue to ad networks). Many apps also transmit basic user IDs to analytics and advertising platforms, creating avenues for surveillance and potential legal requests in abortion-crimes-sensitive contexts. The report highlights that this isn’t just about legality but transparency and user control, and it underscores the lack of a broad US privacy law, calling for stricter regulation. Some apps have improved privacy, but others still collect substantial data and store it in the cloud, raising ongoing privacy concerns.

Firefox 151 Enables Web Serial, Teaming with Adafruit for Browser-Based Hardware

Firefox 151 adds desktop support for the Web Serial API, letting websites read from and write to serial devices via JavaScript. Mozilla and Adafruit are collaborating to validate browser-based hardware workflows, enabling direct hardware communication (e.g., microcontrollers) in the browser with less setup and no extra software for many projects.

Mozilla touts Mythos AI for surfacing 271 Firefox flaws with minimal false positives

Mozilla says Mythos, guided by a custom harness, identified 271 Firefox vulnerabilities in two months with 'almost no false positives,' using the same testing pipeline as human developers. Of these, 180 were sec-high, 80 sec-moderate, and 11 sec-low; 12 Bugzilla reports have been released so far. Critics question cherry-picking and CVE designations, but Mozilla argues the harness plus a second LLM verifier makes AI-assisted discovery scalable and reliable, not marketing.
