## Pricing

from $1.50 / 1,000 results

This Actor is paid per event. You are not charged for the Apify platform usage, but only a fixed price for specific events.
Since this Actor supports Apify Store discounts, the price gets lower the higher subscription plan you have.

## What's an Apify Actor?

An Actor is a serverless cloud program that runs on the Apify platform. It has two run modes.
In Batch mode, an Actor accepts a well-defined JSON input, performs an action which can take anything from a few seconds to a few hours,
and optionally produces a well-defined JSON output, datasets with results, or files in key-value store.
In Standby mode, an Actor provides a web server which can be used as a website, API, or an MCP server.

Apify vocabulary and the platform model are defined once, in the agent quickstart at https://apify.com/agents.md.

## How to integrate an Actor?

If asked about integration, you help developers integrate Actors into their projects.
You adapt to their stack and deliver integrations that are safe, well-documented, and production-ready.

Do not guess an integration path. Every one of them is in the agent quickstart at https://apify.com/agents.md: the Apify MCP server, Agent Skills with the Apify CLI, the JavaScript and Python clients, the REST API, and the account-free path for an agent with no human to sign in. It also carries the rule on stating cost before the first paid run.

For examples already wired to this Actor's own input schema, see the [API](#api) section below.

Each client library has reference documentation the quickstart does not restate: [JavaScript/TypeScript](https://docs.apify.com/api/client/js/docs.md) (`npm install apify-client`) and [Python](https://docs.apify.com/api/client/python/docs.md) (`pip install apify-client`).

### What This Actor Does

Search or browse the Firefox Add-ons store and get a clean record per add-on:

- **Adoption** — **average daily users** and **weekly downloads**
- **Quality** — rating average, rating count and text-review count
- **Author** — name(s), usernames and support email
- **Classification** — categories, tags, type (extension/theme), recommended flag
- **Release** — current version, created and last-updated dates
- **Links** — AMO listing, homepage, support URL, icon

Pick a **search term**, a **category**, or just rank the **top add-ons by users**.

***

### Why Use This

- **Size the market.** Daily users and downloads reveal real adoption across any niche.
- **Track competitors.** Monitor versions, ratings and user counts over time.
- **ASO & keyword research.** See which add-ons rank for a term and why.
- **Developer leads.** Author names, usernames and support emails for outreach.
- **Open and free.** Reads Mozilla's public API — no key, no login, no anti-bot.

***

### Quick Start

#### Run it in the console (no code)

1. Add **search terms** and/or **categories**, or leave empty for the **top add-ons**.
2. Choose a **sort** (users, rating, newest…) and **type** (extension/theme).
3. Set **Max add-ons**, click **Start**, export as **JSON, CSV, Excel or HTML**.

#### Rank a niche by users (Python)

```python
from apify_client import ApifyClient

client = ApifyClient("YOUR_APIFY_TOKEN")

run = client.actor("YOUR_USERNAME/firefox-addons-scraper").call(run_input={
    "searchTerms": ["ad blocker"], "sort": "users", "maxItems": 300,
})
for a in client.dataset(run["defaultDatasetId"]).iterate_items():
    print(a["averageDailyUsers"], "·", a["name"], "·", a["ratingAverage"], "·", a["authorNames"])
```

***

### Input Parameters

| Field | Type | Description |
|---|---|---|
| `searchTerms` | array | Keywords to search add-ons. |
| `categories` | array | AMO category slugs (e.g. `privacy-security`, `shopping`). |
| `sort` | string | `users`, `rating`, `created`, `updated`, `hotness` or `downloads`. |
| `addonType` | string | `extension`, `statictheme`, `dictionary` or `language`. |
| `maxItems` | integer | Max add-ons across all queries. `0` = no limit. |
| `maxPagesPerQuery` | integer | Pagination cap per query (50 per page). |
| `proxyConfiguration` | object | Apify Proxy. Datacenter is enough (public API). |

***

### Output

```json
{
  "id": 607454, "slug": "ublock-origin", "name": "uBlock Origin",
  "type": "extension", "summary": "Finally, an efficient blocker…",
  "averageDailyUsers": 11279732, "weeklyDownloads": 245676,
  "ratingAverage": 4.8, "ratingCount": 22186, "reviewCount": 5868,
  "authorNames": "Raymond Hill", "supportEmail": "",
  "categories": ["privacy-security"], "tags": ["ad blocker", "privacy"],
  "currentVersion": "1.75.0", "lastUpdated": "2026-10-06T16:31:46Z",
  "url": "https://addons.mozilla.org/firefox/addon/ublock-origin/"
}
```

**About coverage:** name, users, downloads, rating, author, version and dates are present for essentially every add-on. Support email is included where the developer publishes one.

***

### Use Cases

1. **Add-on market intelligence** — size niches by users/downloads and track leaders.
2. **Competitive monitoring** — watch versions, ratings and adoption over time.
3. **ASO & keyword research** — see what ranks for a term and how it's categorised.
4. **Developer lead generation** — author names, usernames and support emails.

***

### Tips

- **`sort: "users"`** ranks by adoption; **`hotness`** surfaces trending add-ons.
- Leave searches empty to pull the **top add-ons overall**.
- **`categories`** browse uses AMO slugs (e.g. `privacy-security`, `tabs`, `shopping`).
- **`weeklyDownloads`** + **`averageDailyUsers`** together show momentum vs installed base.
- **Schedule it** with Apify Schedules to track a niche over time.

***

### Frequently Asked Questions

**Do I need an account or key?**
No. The addons.mozilla.org API is public and free — no login, key or anti-bot.

**Can I get themes, not just extensions?**
Yes — set `addonType` to `statictheme` (or dictionary/language).

**How do I find top add-ons without a search?**
Leave `searchTerms` and `categories` empty and keep `sort: "users"`.

**Does it include the Chrome Web Store?**
No — this covers Firefox Add-ons (AMO), which offers a public API.

**What export formats are supported?**
JSON, CSV, Excel, HTML, or via API — plus Google Sheets, webhooks, Make and Zapier.

## CLI example

echo '{
  "searchTerms": [
    "vpn"
  ],
  "maxItems": 150,
  "proxyConfiguration": {
    "useApifyProxy": true

## MCP server setup

```json
{
    "mcpServers": {
        "apify": {
            "type": "http",
            "url": "https://mcp.apify.com/?tools=fetch-actor-details,haketa/firefox-addons-scraper"
        }
    }
}
```

The hosted server signs you in with OAuth on first connect, so no API token belongs in this config. Clients without OAuth support can send an `Authorization: Bearer <APIFY_API_TOKEN>` header instead, using a token from API & Integrations in Apify Console (https://console.apify.com/settings/integrations).
