Browser Extensions

Privacy-focused add-ons for every browser

No ads, no tracking, just tools that work. Available on Firefox, Chrome, and Edge.

SHEET 01 · Overview

Browser extensions that respect your browser

Browser extensions have a reputation for creeping scope - starting as a simple tool, then sprouting analytics, "personalisation", and affiliate hooks a few versions later - and ours don't: every add-on on this page asks for the minimum permissions it actually needs, ships without ad-tech or third-party scripts, and is maintained through the manifest changes that keep breaking other people's extensions. Whether you're looking for a maintained RSS reader extension, proper browser fingerprint protection, parental controls for a family device, or a tidy EPUB reader for Thunderbird, you'll find something here that works across Firefox, Chrome, Microsoft Edge, and Thunderbird without a subscription.

SHEET 03 · Browser support

Which browsers are supported, and how

Firefox is the primary target for everything we ship - it's where Digital Fracture development started and it's still the browser with the strongest extension API for privacy work, so every add-on on this page is available there (including Fingerprint Defender and Parental Whitelist, which rely on Firefox-only permissions). Chrome and Microsoft Edge both run RSS Kit Pro and RSS Ninja, kept current with the Chrome Web Store and Edge Add-ons review cycles and fully Manifest V3 compliant. Thunderbird has its own pair - RSS Ninja for Thunderbird and Epub Ninja - built natively against the Thunderbird WebExtension APIs rather than ported from the browser versions. Every extension ships with minimum permissions, no third-party trackers, and no remote code loading; if you'd like to audit what one is doing, the XPI or CRX package is plain-text JavaScript, because we don't compile or obfuscate our builds.
