In code review (v4.10.7)

Our reviewer read version 4.10.7 — the most recent version we have reviewed — and found no malicious behaviour. The version shown here has not been individually reviewed yet.

What our analysis found

HeadingsMap, used by 100,000 people, showed no malicious code in Extension Auditor's review. Its permissions mean it can read and change data on all websites. It comes from a trusted publisher and was last updated in September 2026.

Analyst notes

The extension is a well-established developer tool for analyzing heading structures and landmarks, with a 6-year history, 100k+ users, positive ratings, and a low-risk publisher. The code performs only client-side DOM analysis and extension UI injection; all network requests are to the extension's own bundled resources (CSS, HTML, locales). Browser permissions (activeTab, storage, webNavigation, <all_urls>) are necessary for its documented functionality. No data exfiltration, remote code execution, or suspicious behavior is present.

About this extension

To show, browse and audit (for accessibility and SEO) the headings structure

Read the publisher’s full description

The extension generates a document map or index of any web document structured with headings, allowing direct access to content by clicking on any of its items. It now also displays the Landmarks analysis. Although the extension was initially meant to assist web developers, consultants, and accessibility auditors, it turned to be useful for many users, facilitating the reading and navigation in long structured pages Features: * Lists headings with optional information about their levels and any breaks in the correct hierarchical structure. * Lists sections with header information, including optional details about structural errors. * Lists the landmarks and can identify details about them, and optionally details about structural errors. * Provides information from the main document and documents within frames, featuring a document selector when multiple documents are present. * Clicking on headers scrolls the document to the corresponding position and highlights it. * Detects changes in the DOM and updates content as necessary, with an option for manual refresh. * Allows collapsing of the header list by levels. * CSS outline for identifying headers or sections when clicking the tree. * Does not display hidden headers or sections (hidden from assistive technologies). * If a header or section is an anchor, the link in the results points to it. This is useful for copying directly from the tree using the browser's contextual menu. Optionally, it shows anchor-links that copy the link to the clipboard when clicked. * Two themes available.
