Firefox is now the last major browser that still supports uBlock Origin

📝 Discussion Summary (Click to expand)

Four dominant themes emerging from the Hacker News thread

1. A single, custom extension can replace multiple “standard” ones

“Anyone can build a custom extension to do anything an extension is allowed to do. … I’ve been using Claude code to build a single custom extension that handles all of the things I used 7 extensions for previously.” — spottedmarley

Users see the ability to stitch together features into one tightly scoped extension (or AI‑generated tool) as a major productivity win.

2. Manifest V3 limits Chrome’s ad‑blocking power and pushes users toward alternatives

“Manifest V3 is why I finally shut down Sitetruth and Ad Limiter. Removing ads from Google Search is now possible only in Firefox.” — Animats
“Manifest V3 working as intended.” — rwz

Chrome’s shift to Manifest V3 is repeatedly cited as the reason ad‑blockers lose effectiveness, prompting many to migrate to browsers that still support MV2 (e.g., Brave, Vivaldi) or to Firefox.

3. Trust in Mozilla’s extension‑vetting process vs. concerns over data collection

“Firefox is also the only browser that vets uBlock's code on every update to make sure the developer hasn’t inserted spyware or malware into the extension.” — swed420
“They could save themselves the trouble if Firefox simply baked in its own ad‑blocking, but since Google basically owns them, we all know that will never happen.” — rwz

The community values Firefox’s manual review of popular extensions like uBlock Origin, even while debating Mozilla’s broader telemetry and data‑sharing policies.

4. Firefox’s declining relevance and the fight to keep an open, ad‑blocking browser alive

“Firefox, after 20 years, once again has an advantage over the other browsers. Let's hope for new generations to get tired of so many ads to finally ditch Chrome.” — timetraveller26
“It’s fine but I find they EOL devices/OS's earlier than Firefox.” — jollyllama

Many commenters lament the shrinking user base of Firefox, warn that reliance on Chromium‑based browsers hands too much control to Google, and stress the need for a vibrant, privacy‑focused alternative.

AI-Extension Fusion Platform

Summary

  • AI‑Extension Fusion Platform lets users describe the combined functionality of multiple favorite extensions and automatically generates a single Manifest V3 extension that replaces them, solving extension overload.
  • Core value: One‑stop, vetted extension builder that works across Chrome, Edge, and Firefox without manual coding.

Details

Key Value
Target Audience Power users, privacy‑conscious individuals, and developers who rely on many browser extensions
Core Feature Generates a unified, policy‑compliant extension from plain‑language spec and optionally incorporates code patterns from installed extensions
Tech Stack Node.js backend, GPT‑4 API for code generation, React front‑end, Chrome/Firefox extension host
Difficulty Medium
Monetization Revenue-ready: Subscription (e.g., $9/mo)

Notes

  • HN users like spottedmarley emphasized “single custom extension that handles all of the things I used 7 extensions for previously,” showing clear demand for consolidation.
  • Potential for community‑driven template libraries and a monetizable SaaS offering premium rule sets.

Unified Declarative Filter Engine (UDEF)

Summary

  • A cross‑browser ad‑blocking engine that provides a unified declarative filter API compatible with Manifest V3, letting users apply the same rule set on Chrome, Edge, and Firefox.
  • Core value: Consistent, lightweight ad‑blocking across browsers without maintaining separate extensions.

Details

Key Value
Target Audience Users frustrated with fragmented ad‑blocking across browsers, especially those moving from Chrome to Firefox
Core Feature Unified filter engine exposing a simple JSON rule format that works in any V3‑compatible browser, backed by community‑maintained filter lists
Tech Stack Rust compiled WebExtension, WebAssembly for rule processing, JSON schemas, optional CLI for filter updates
Difficulty High
Monetization Hobby

Notes

  • Commenters repeatedly lamented that “Manifest V3 ... destroys the APIs so that they’re useless,” indicating a clear need for a V3‑compatible solution.
  • Could spark discussion on open‑source ad‑block standards and attract contributors looking to preserve effective filtering.

Extension Trust Hub

Summary

  • A marketplace and automated vetting service that signs extensions, runs static and runtime security analysis, and awards a “Verified” badge, giving users confidence similar to Firefox’s recommended extensions but across all browsers.
  • Core value: Trustworthy extension distribution that reduces fear of malicious updates.

Details

Key Value
Target Audience Security‑conscious users, developers, and enterprises seeking safe extension installation
Core Feature Automated security review, permission audit, and continuous monitoring of extension updates
Tech Stack Python backend with CI pipelines, Docker, React front‑end, REST API for browser integration
Difficulty Medium
Monetization Revenue-ready: Transaction fee (2% per paid extension sale)

Notes

  • HN discussion highlighted distrust of extension maintenance (“they could insert spyware”), making a verification layer highly relevant.
  • Could foster dialogue on improving extension safety standards and potentially be adopted by browsers as an optional verification channel.
