User reviews

HeadingsMap is praised for its effectiveness in visualizing heading hierarchies, aiding SEO and accessibility testing, and its simplicity. Users appreciate its utility for screen readers and academic work. However, multiple users report issues with the extension not loading on many sites, the removal of a key HTML5 feature, conflicts with other apps like Google Calendar and Facebook, and lack of developer support. Some also find the heading numbers in the table of contents distracting and seek ways to customize it.

Pros

Effectively visualizes the heading hierarchy (H1-H6) of web pages, aiding SEO and accessibility testing.
Highly useful for accessibility purposes, especially for screen-reader users and compliance testing.
Simple to use with no major issues for many users, providing a clear overview of page structures.
Supported by multiple users for web development and academic reading to navigate and understand complex documents.
Fast and accurate heading analysis compared to other similar tools.

Cons

Sometimes the extension fails to load the headings map on many websites, limiting its reliability.
Recent updates removed the HTML5 heading and section analysis feature, which many users found essential.
Conflicts with other web applications, e.g., causes issues in Google Calendar and text area inputs on Facebook.
Lack of support and responsiveness from developers when issues occur, causing frustration among users.
Headings numbering in the generated table of contents can't be hidden or customized, which some users find distracting.

I installed HeadingsMap on the Vivaldi browser. However when I click the HeadingMaps button on the toolbar, the table of contents (headings) does not appear as side panel. I installed it also in the Brave browser (also Chromium-based) and the side panel appears. Is HeadingMaps supported on Vivaldi?

Extension safety

Risk impact

Risk impact measures the level of extra permissions an extension has access to. A low risk impact extension cannot do much harms, whereas a high risk impact extension can do a lot of damage like stealing your password, bypassing your security settings, and accessing your personal data. High risk impact extensions are not necessarily malicious. However, if they do turn malicious, they can be very harmful.

HeadingsMap requires some sensitive permissions that could impact your browser and data security. Exercise caution before installing.

Risk impact analysis details

Critical Allows access to all websites, posing a significant security risk as it can monitor and modify data from any visited site.

Risk likelihood

Risk likelihood measures the probability that a Chrome extension may turn malicious. This is determined by the publisher and the Chrome extension reputation on Chrome Web Store, the amount of time the Chrome extension has been around, and other signals about the Chrome extension. Our algorithms are not perfect, and are subject to change as we discover new ways to detect malicious extensions. We recommend that you always exercise caution when installing a Chrome extension.

HeadingsMap has earned a fairly good reputation and likely can be trusted.
