Get Started in 3 Easy Steps
- 01
Check the Listing and Permission Scope
Confirm the developer identity, version, update date, and every requested permission on Mozilla. Authority Specialist proprietary data assigns 1 minute to installation, but that timing is only an estimate.
- 02
Test Against a Page With Known Markup
Allow 30 seconds for the target page to load, then use a page whose title, headings, links, and canonical are already documented. A controlled page lets you distinguish extension behavior from unknown client-side conditions.
- 03
Document Findings and Escalation Needs
Allow 3 to 5 minutes to review the dashboard. Record each output, its apparent source, and every mismatch. Send indexation, security, or compliance questions to the primary system that can answer them.

Why Use Open SEO Stats for Firefox?
- Quick Access to Common Page SignalsThe extension can place several on-page fields in one Firefox workflow, which is useful when the goal is rapid triage rather than final diagnosis. Compared with opening multiple browser panels for an initial review.
- A Defined Path From Triage to EvidenceThis review separates convenience outputs from questions that require source code, headers, Search Console, logs, or a crawler. That boundary helps prevent an extension result from being treated as conclusive evidence. Compared with using one browser extension as a complete audit.
- Time-Stamped Listing InformationThe review identifies the checked version, user count, review count, package size, update date, and permissions so readers can distinguish dated listing facts from durable diagnostic guidance. Compared with software coverage that omits its observation date.
Frequently Asked Questions
Should a team consider Open SEO Stats for Firefox safe?
This review does not certify the extension as safe. Mozilla lists access to website data, tabs, downloads, and download history. Compare the current permissions with your policy and test the extension in a controlled browser profile before broader deployment.
Which Open SEO Stats outputs can be verified directly?
Fields taken from the page, such as titles, headings, links, and canonical tags, can be checked against source code or the rendered document. Third-party estimates may differ from primary systems, so important decisions should rely on Search Console, logs, headers, or crawl evidence.
Can Open SEO Stats replace a technical SEO audit?
No. It is a page-level triage tool, not a site-wide audit system. It cannot crawl the full site, expose Google-selected canonical decisions, verify a legal identity, or reveal which content trained a model.
Does Open SEO Stats report AI citations or model training data?
No verified claim in the listing supports either capability. AI mentions require a separate process that records the model, query, date, locale, and repeated observations. The extension does not expose model training data.
