📢 Ad Blocker Developer Summit 2026 is less than two weeks away!

On November 3–4, ad blocker developers, browser engineers, filter list maintainers, and privacy researchers will gather in Copenhagen under our original name — and for the first time ever, the summit will run across two stages.

This year, we have five speakers from AdGuard in the lineup — but we’re saving them for dessert and will tell you all about their talks in a separate post. For now, here is a taste of what our guest speakers are bringing to the table:

• Oliver Dunk and Devlin Cronin (Google) — What’s new in Chrome. A summit classic: direct updates from the Chrome Extensions team on where the platform is heading. Also from Google, Thomas Steiner will dive into cross-origin storage and blocking hashes

• Cornelius Witt (eyeo) — The AI industry is about to repeat all the mistakes of the ad blocking wars. Our co-organizers at eyeo are also bringing talks by Wen-Yu Chung on differentially private attribution and Michelle McDowell on user misconceptions about home network privacy

• Summit regulars and fresh faces — We’re excited to welcome back familiar faces like Anton Lazarev and Ryan Brown (Brave), Sam Macbeth (DuckDuckGo), Tina Chenska (Opera), Rob Wu (Mozilla), and Cameron Eckelberry and Mohamed Elgendi (Malwarebytes). At the same time, plenty of first-timers are making their summit debut — including Ajay Ramachandran (SponsorBlock), Babak Farrokhi (Quad9) and Thomas Steiner (Google)

• Our first-ever Privacy Panel — In past years, we’ve hosted panels on browsers and filters. This time, alongside our traditional Browser Panel, we’re running a dedicated Privacy Panel for the very first time to discuss why everyone agrees we need privacy-enhancing tech — yet almost nobody uses it

Swipe the cards to meet some of our guest speakers — and tomorrow, we’ll share what Team AdGuard is bringing to the stage!

🎤 Yesterday we introduced some of our guest speakers for Ad Blocker Dev Summit 2026. Today, let’s look at what Team AdGuard is bringing to Copenhagen on November 3–4!

From AI-driven fingerprinting to CNAME cloaking and Apple Mail trackers, our team is tackling some of the trickiest problems in ad blocking right now:

• Natalia Sokolova (UX Writer at AdGuard) — The shadow theater: Frontend persona spoofing against AI-driven network and behavioral fingerprinting. How trackers use AI to profile your behavior — and how we can fool them.

• Elizaveta Egorova (Software Engineer, AdGuard) and Dmitrii Seregin (Team Lead Filters Infra, AdGuard) — How to extend the CNAME list: Finding trackers hidden behind proxies. A deep look into uncovering disguised trackers that try to bypass filter lists.

• Maxim Topciu (Browser Extensions Team Lead) — Automating filter reports with an AI agent. How AI agents can help filter developers process user reports faster and keep filter lists sharp.

• Evgenii Neshumov (Project Manager) — Blocking without feedback: Mail tracker protection inside Apple Mail. What it takes to block hidden email trackers when the mail client gives you almost zero feedback.

• And as a special bonus: Alongside our speakers, AdGuard’s CTO and co-founder Andrey Meshkov will take the stage to moderate the fan-favorite Browser Panel, bringing together engineers from Google, Mozilla, Brave, Opera, and DuckDuckGo.
