Overview
Firefox Add-ons Scraper
Scrape Firefox Add-ons from any search query, up to a million per run. Every extension comes with its name, author, rating, user count, and version. No browser extension or API key required. Export to CSV, JSON, Excel, or XML.
Mozilla's Firefox Add-ons marketplace has no public API for bulk data access, making large-scale research tedious. This actor searches the public extension listings directly by keyword and returns structured results. You get a clean dataset of add-on metadata without writing a single scraper.
| Who uses it | What they scrape Firefox Add-ons for |
|---|---|
| Market researchers | Analyze the competitive landscape of browser extensions for a specific keyword. |
| Extension developers | Monitor competitor ratings, user counts, and update frequency in their niche. |
| Security analysts | Audit available extensions for a given functionality to identify potential risks. |
| Content curators | Build a directory of recommended Firefox Add-ons for a blog or newsletter. |
What it does
This Actor collects Firefox Add-ons by search term and returns each extension as a flat row with its metadata.
- 🔍 Keyword search: Provide any search term, like 'dark mode' or 'ad blocker', to scrape matching add-ons.
- 📊 Structured output: Each result is a flat row with a consistent schema, ready for analysis.
- 📈 Scalable collection: Set a maximum from 1 to 1,000,000 add-ons to control the size of your dataset.
Results export to CSV, JSON, Excel, or XML, or straight from the API.

"maxItems": 10
}
A larger pull:
{
"searchQuery": "dark mode",
"maxItems": 200
}

Run it

Use with AI agents (MCP)
Give an AI agent live access to Firefox Add-ons through the Model Context Protocol. Add the Actor to Claude, Cursor, or any MCP client:

Then prompt it in plain language to run the scraper and read back the results.
Troubleshooting
Why am I getting no results?
Your search query might be too specific or contain a typo. Try a broader or more common term, like 'weather' instead of 'weather forecast widget'.
The run finished but collected fewer add-ons than my maxItems setting.
This is normal. The actor stops when it has collected your requested maximum or when there are no more search results for your query, whichever comes first.
I'm getting an error that the search query is required.
You must provide a value for the 'Search term for add-ons' field in the input. It cannot be left empty.
The data looks different from what I see on the website.
The Firefox Add-ons website may have changed its layout. If the output is missing fields, try re-running the actor. If the issue persists, it may need an update.
The actor is timing out.
If you are requesting a very large number of add-ons, try increasing the run's timeout setting in the Apify console, or reduce the maxItems value.
