A11y Lens Firefox

A11y Lens

Accessibility checker powered by axe-core. Scan any page for WCAG violations and highlight offending elements.

Features & Capabilities

A11y Lens is a complete accessibility auditing toolkit inside your browser's DevTools. It combines automated scanning (powered by axe-core, the open-source engine behind Lighthouse) with guided manual testing —because automated tools alone catch only 30–50% of WCAG issues.

Automated scanning — one-click axe-core audit (WCAG 2.0/2.1/2.2 AA rule sets, iframes and shadow DOM included), findings sorted by severity with the offending HTML, per-element selectors, and copy-ready fixsuggestions (HTML/React/Vue). Contrast failures include a computed passing color. Preview any fix live on the page with undo, or auto-fix the whole page temporarily to verify.

🇦🇪 UAE Design System (DLS) audit — 13 checks against the official AEGov design system (mandated for UAE federal entities): component adoption, fonts, type scale, the real 115-token color palette with nearest-token suggestions, bilingual/RTL requirements, and button sizing — with on-page gap highlighting and fixes.

Guided manual tests — 10 step-by-step wizards (keyboard, focus, headings, landmarks, alt-text quality, zoom, screen readers, motion, forms); every "No" becomes a recorded finding with an element you pick on the page.

More: user-flow recording across pages and states, two-way navigation (click a finding ↔ click a highlighted element), scan history with trend charts, violation search, and exports: HTML/PDF reports with annotated screenshots, JSON, CSV, GitHub issues, Jira and Azure DevOps import files. Full Arabic interface (RTL) including all test content.

Firefox note: the color-contrast eyedropper is unavailable in Firefox (no EyeDropper API) — the panel shows a notice; everything else works identically.

Privacy: everything runs locally. No data is collected or transmitted.

Is A11y Lens Safe?

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.

A11y Lens requires a few sensitive permissions. 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.
  • Medium ****** ** ********* ****** ********* *** **** ****** **** **** ** ******* ** ********** **** ***********
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 Add-ons Store, 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.

A11y Lens is recently added, and hasn't been around long enough for us to gather enough data to accurately assess its risk level.
