Save the date! The Mozilla Meetup series continues with talks focused on modern web technologies. To account for typical **no-show rates**, we’ve opened more RSVP spots than we can physically accommodate. Based on our last event, only about 36 of 100 registered participants (including Mozillians) attended in person. **We will admit attendees on a first-come, first-served basis and will need to close the doors once we reach room capacity (around 50 people).** Note that this event operates under the [Mozilla Community Participation Guidelines](https://www.mozilla.org/about/governance/policies/participation/). **18:00 - Doors open** **18:30 - Keep Off My LAN: Firefox's Implementation of Local Network Access** In June 2025, researchers exposed Local Mess — a tracking vulnerability where Meta Pixel and Yandex Metrica scripts abused localhost access to silently track millions of Android users across the web. The web platform had a long-standing hole, and Firefox moved quickly to help close it. This talk presents Local Network Access (LNA), the emerging standard that finally tackles these threats along with a backlog of security vulnerabilities tied to localhost and local network devices. It walks through the specification, Firefox's implementation, and the real-world deployment challenges encountered along the way and how they were mitigated. Beyond the "what," this talk opens up a conversation. As LNA is still taking shape in the WICG, it's a chance for people building in the local network and localhost space — and for the adblocker and anti-tracking community, especially those running DNS-based blockers (Pi-hole, AdGuard Home, and similar) — to surface edge cases, breakage, and threat models that should be designed for. Anyone running services on localhost / local network, or operating local DNS-based tracking protection, is invited to share what LNA needs to get right. About the speaker: Sunil Mayya is a software engineer on Mozilla's Firefox Networking team, based in Nuremberg, and a core contributor to Firefox's implementation of the Local Network Access standard. **19:30 - The Devil is in the Defaults - what to do about XSS** This session is about latest defenses against Cross-Site Scritping (XSS), the most prevalent security issue of all times. We will showcase typical XSS bugs and how they can be avoided. We will also explain why previous mechanisms fall short of protecting web sites at scale and why we believe Trusted Types and the Sanitizer API can help closing this gap. The presentation will also give hands-on advice to enable security and development teams adopting these new protections. We will close with a bit on security considerations and remaining risks. About the speaker: Frederik Braun is a security engineer and manager working on Firefox.

**Rust Berlin on location 🏳️‍🌈** is a new, informal in-person Rust meetup group in Berlin. We are a interactive meetup format interested in mob coding, deep diving and problem solving together. We build toy projects, share experiences, discuss technology and learn new cool stuff. And you are welcome to join! No matter if you are writing Rust production code every day, if you already contribute to Open Source projects or want to start doing so, if you use Rust in hobby projects or if you are just curious what the hype and buzz is all about, you are very welcome! To coordinate and plan activities, please join our **[Rust Berlin on location 🏳️‍🌈](https://rust-berlin.zulipchat.com/join/gap4pdbz7xsquliiz7tgcyuk/)**[ Zulip chat](https://rust-berlin.zulipchat.com/join/gap4pdbz7xsquliiz7tgcyuk/)! **Planned programme** Being an informal meetup, we are open to anything between just meet and talk, explore nerd snipes and rabbit holes, mob code together, plan and build fun projects, tinker with electronics, and presentations with Q&A. With the [introduction](https://berline.rs/2026/04/01/berlin-talks.html) of the new [Rust Berlin Talks](https://berline.rs/about#rust-berlin-talks) meetup series, **[Rust Berlin on location 🏳️‍🌈](https://berline.rs/about#rust-berlin-on-location)** strengthens its focus on social community experience, the exchange of knowledge, ideas and perspectives, and the joy of spontaneity. This time, Florian Gilcher will give a small **workshop on structured and safe usage of *\`unsafe\`***. We will look at some common use-cases and how common hazards can be avoided. Anyone is invited to bring their projects and questions, show something, ask something, or explore a topic together. The best conversations and deepest rabbit holes can emerge out of seemingly nowhere. **Projected upcoming meetups** We schedule regular meetups on Thursday evening every four weeks, using the slot between the Berlin Rust Hack and Learn online meetup (every two weeks), and the Rust Nuremberg online meetup (every four weeks). 11 June 2026 is our fourteenth meeting Our next projected meetings are going to occur on the following dates: * 9 Jul 2026 * 6 Aug 2026 * 3 Sep 2026 * 1 Oct 2026 * 29 Oct 2026 * 26 Nov 2026 **Location** Our meetup location is the new shared office community space of Ferrous Systems, Slint and KDAB in Berlin Mitte, for up to 25 people. We are expecting to use this space as our default location for the time being, with the IN-Berlin e.V. community space in Moabit as backup. Regardless, as our group might eventually outgrow the locations' size limit, we are low-key looking for bigger locations. If you know a fitting location, then please let us know in our Signal group! Another workable way might be to split the meetup into smaller, interest-specific sub-groups instead. As the no-show rate on Meetup.com is rather high, consider showing up even if you are on the waiting list. We can't promise that there is any space left, but usually there is. So give it a shot! **Accessibility** The location has an elevator and a wheelchair accessible bathroom. Please note that the bathroom is two floors down from the meetup space. On our quest for a bigger location, we are going to pay special attention to accessibility. **Community** We aim to create a safe place for everyone and adhere to the [Berlin Code of Conduct](https://berlincodeofconduct.org/). Inclusivity is very important to us. If you are curious about Rust, but unsure if you are welcome to join: Yes, yes you are. Please come to the meetup! If you have special needs, please get in contact, we will try to accommodate you as best we can. We are part of [https://berline.rs/](https://berline.rs/) and like to hang out in the **[Rust Berlin on location 🏳️‍🌈](https://rust-berlin.zulipchat.com/join/gap4pdbz7xsquliiz7tgcyuk/)**[ Zulip chat](https://rust-berlin.zulipchat.com/join/gap4pdbz7xsquliiz7tgcyuk/). You are very welcome to join!

Private Group. Closed to the Public Knowing ourselves and understanding our abilities is the first step toward wielding our gifts with control and accuracy. In subsequent classes we will verify and hone our talents with activities and discussion. These are hands-on workshops and participation is expected. The goal of our series will be to develop expertise in areas of particular interest such as mediumship, channeling, divination, healing and, etc.. Our ultimate directions will be determined by class members as we evolve. I look forward to sharing and discovering with you. - Cynthia
