The Page Structure Chrome extension provides web developers and accessibility evaluators an intuitive way to assess a web page's structural compliance with accessibility standards like WCAG 2.1 and WAI-ARIA 1.2. By leveraging the Firefox Sidebar, users can view the page title, hierarchical HTML headings, and ARIA landmark regions all at once.

This tool is invaluable for ensuring that screen reader users receive an accurate overview of page content and landmarks, facilitating efficient navigation. Headings and landmarks are clearly presented and can be selected to highlight and scroll to the respective element on the page. This helps authors fine-tune content labeling and structure to enhance accessibility and user experience for people with visual impairments.

That is great! Awesome! I have replaced other extensions related to 'Headings, TOC, Outline' with it. The interface also needs to be full of browser height; Please refer to the style of "Outline sidebar" for font size, perhaps for a better experience Feature request: 1. Filter search box 2. Dark Theme 3. Scroll Spy (When the page scrolls, the interface indicates the corresponding title) 4. Temporary favorite symbols (click on the heading title left side, highlight heading tag), and also add favorite symbols in appropriate positions on the page.

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.

Page Structure 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 Firefox add-on may turn malicious. This is determined by the publisher and the Firefox add-on reputation on Firefox Browser Add-ons, the amount of time the Firefox add-on has been around, and other signals about the Firefox add-on. 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 Firefox add-on.

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