Browser Extension

Verify Technical Authority Directly from Your Firefox Browser

Access transparent SEO metrics and server data to audit websites in regulated industries without leaving your current tab.

Updated April 13, 2026

Quick Answer

What is Open SEO Stats for Firefox?

Open SEO Stats for Firefox is a browser extension that surfaces technical SEO signals directly in the toolbar: page indexation status, canonical tags, meta robots directives, server response headers, and basic on-page metrics without leaving the current tab.

For regulated-industry auditors, it is a useful first-pass tool for verifying technical directives on individual URLs during manual review, particularly when checking canonical implementation or noindex status across a site's key pages.

Its limitations are significant for enterprise work: it does not crawl at scale, cannot surface entity authority signals, and provides no E-E-A-T or schema validation. It functions best as a spot-check companion to a full crawl platform rather than a standalone audit solution.

FAQ

Frequently Asked Questions

In my experience, browser extensions from reputable sources that focus on public data are generally safe. Open SEO Stats focuses on aggregating information that is already publicly available on the web.

It does not require you to log into your site's backend or provide sensitive credentials. However, as with any extension, you should review the permissions it requests during installation to ensure they align with your firm's security policies.

The accuracy of the data depends on the third-party sources it pulls from, such as search engine indexes and link databases. While these numbers are excellent for identifying trends and performing preliminary audits, they should be viewed as estimates rather than absolute figures.

For high-stakes decisions, I always recommend cross-referencing this data with direct tools like Google Search Console or a deep-dive technical crawl.

No, it does not. A full SEO audit involves a deep-dive into site architecture, content quality, and entity authority. Open SEO Stats is a diagnostic tool for quick verification and discovery. It is the first step in a process, not the final word.

I use it to identify 'red flags' or areas that require further investigation. It is a component of a larger, documented system for managing visibility.
