Firefox Add-ons Reviews Scraper

Export public reviews and star ratings from Mozilla Firefox Add-ons by add-on URL, slug, or numeric ID.

Use this actor to monitor extension reputation, compare competitor feedback, and build repeatable review exports from the official Mozilla Add-ons public API.

What does Firefox Add-ons Reviews Scraper do?

Firefox Add-ons Reviews Scraper collects individual rating and review records from addons.mozilla.org.

It accepts Firefox add-on URLs such as https://addons.mozilla.org/en-US/firefox/addon/ublock-origin/ or slugs such as ublock-origin.

For every saved review or rating, the actor outputs add-on metadata, rating score, review text when present, reviewer profile fields, version information, source URLs, and scrape timestamps.

The actor uses Mozilla's public JSON API, so it does not require a Firefox account, browser automation, or credentials.

Who is it for?

• 🧩 Browser extension product teams tracking release feedback.
• 📈 SEO and app-market researchers comparing extension reputation.
• 🛡️ Trust and safety teams watching negative review spikes.
• 🧪 QA teams checking whether new versions trigger user complaints.
• 🧑‍💼 Agencies reporting Firefox add-on sentiment to clients.
• 🧭 Competitive intelligence teams monitoring rival extensions.

Why use this actor?

Manual review checking is slow and inconsistent.

Firefox Add-ons Reviews Scraper turns review pages into structured datasets that can be filtered, joined, scheduled, and exported.

You can run it daily for a small list of add-ons, export thousands of reviews for deeper research, or feed the output into dashboards and alerting workflows.

Data you can extract

Field	Description
addonSlug	Firefox Add-ons slug
addonName	Localized add-on name
reviewId	Mozilla review/rating identifier
score	1-5 star rating
body	Written review text, when available
createdAt	Review creation timestamp
userName	Reviewer display name
userUrl	Reviewer profile URL
version	Add-on version tied to the review
reviewUrl	Public review URL
sourceUrl	API page used for the record
scrapedAt	Actor scrape timestamp

How much does it cost to scrape Firefox Add-ons reviews?

The actor uses pay-per-event pricing.

There is a small run start event and a per-review event for each dataset item saved.

The default public pricing is designed for monitoring workloads and bulk exports.

You can control cost with maxReviewsPerAddon and by limiting the number of add-ons per run.
