WebNarrator Firefox

WebNarrator

Select any text on any webpage, hit 'play', hear it read aloud with live word-by-word highlighting. Uses your OS's installed voices. No cloud, no tracking, no data collected, works offline.

Features & Capabilities

WebNarrator is a privacy-first text-to-speech reader that uses your operating system's built-in voices. No cloud APIs, no tracking, no data collection. Everything runs locally on your device.

How to use it

Select any text on any webpage. Press Alt + Shift + S (or ⌥ + ⇧ + S on macOS) or right-click and choose "Read selected text aloud". The current word highlights in yellow as it's spoken. The toolbar popup gives you play / pause / stop controls, a 0.5× to 2.5× speed slider, and a voice picker for any TTS voice your OS has installed.

What makes it different

• Live word-level highlighting: see exactly what's being spoken, on the page itself, not in a separate sidebar. • Works everywhere: articles, docs, blog posts, social media, code-heavy pages, math notation (KaTeX / MathJax), and iframe-embedded content (LeetCode, embedded readers, etc.). • Customizable keyboard shortcut: configure at about:addons → Manage Extension Shortcuts. • Light and dark themes: follows your OS preference automatically, or pick manually. • No internet required: speech is generated by your OS, on your device. Disconnect from Wi-Fi and WebNarrator works exactly the same.

Privacy: no data collected

WebNarrator collects, stores, and transmits zero user data. No analytics, no telemetry, no tracking pixels, no cloud calls of any kind. The only things saved locally are your voice choice, your speech rate, and your light/dark theme preference, all stored in your browser, never sent anywhere.

A note on voice quality

WebNarrator uses whatever voices your operating system has installed. Most operating systems ship with one or two basic voices and require you to download the high-quality "premium" or "neural" voices separately. If WebNarrator sounds robotic out of the box, you almost certainly have only the basic voices installed.

Is WebNarrator 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.

WebNarrator 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.
  • High ******* ******* **** *** ****** ***** *** ***** ** ******* **** ********* ********* ** * *********** *****
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.

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

Risk likelihood analysis details
  • High This extension has low user count. Unpopular extensions may not be stable or safe.
  • Medium **** ********* *** ******* ** *** **** * ******* *** ******* *** *** ** ****** ** *****
  • Medium **** ********* *** ***** ** *** **** * ******* *** ********** *** *** ** ****** ** *****
