Firefox Add-ons Scraper 🦊🧩

Scrape Firefox add-ons (browser extensions & themes) straight from the official Mozilla Add-ons store — addons.mozilla.org (AMO) — as clean, structured JSON. Get daily active users, ratings, review counts, weekly downloads, current version and author for any extension. No API key, no login.

👉 Run it on Apify »

What it does

Two modes:

• search — paginate the AMO search API for a keyword (e.g. ad blocker, dark mode, password manager) and collect up to maxItems add-ons.
• addons — fetch specific add-ons by their slug (the last part of an add-on URL, e.g. ublock-origin) or GUID.

One dataset row per add-on. Runs on datacenter proxies (or no proxy at all) — the AMO API is a clean public JSON endpoint.

Input

Field	Type	Description
mode	select	search (keyword) or addons (specific slugs/GUIDs)
query	string	Search keyword when mode = search. Default ad blocker
slugs	array of string	Add-on slugs or GUIDs when mode = addons, e.g. ["ublock-origin"]
maxItems	integer	Max add-ons to return (1–1000, default 100)

Example input

{
  "mode": "search",
  "query": "ad blocker",
  "maxItems": 100
}

{
  "mode": "addons",
  "slugs": ["ublock-origin", "darkreader", "firefox@ghostery.com"]
}

Output

Each item:

{
  "id": 607454,
  "name": "uBlock Origin",
  "slug": "ublock-origin",
  "summary": "An efficient blocker add-on for various browsers. Fast, potent, and lean.",
  "type": "extension",
  "users": 10619125,
  "weekly_downloads": 212319,
  "rating": 4.8006,

  "scraped_at": "2026-07-18T08:00:00+00:00"
}

Every field is nullable. users is average daily users; rating is the average star rating (0–5); rating_count is the number of ratings.

Pricing

Pay-per-usage. Roughly ~$1 per 1,000 add-ons scraped on the Apify platform (exact cost depends on your plan and proxy usage — this actor is datacenter-friendly and light on compute).

• Competitor intelligence — track rivals' user counts, ratings and version cadence over time.
• Developer analytics — monitor your own extension's adoption and reviews.
