Markdown Viewer Pro Firefox

Markdown Viewer Pro

The cleanest way to read Markdown in Firefox — open any .md file locally or on the web and get a beautifully rendered, fully interactive document instantly.

Features & Capabilities

✨ Why Markdown Viewer Pro?

Most browsers show Markdown files as raw, unformatted text. Markdown Viewer Pro transforms them into polished, readable documents — with zero configuration required. Whether you're reviewing a project README, reading documentation, or writing notes, your files look exactly as intended.

🚀 Key Features

Beautiful Rendering

  • GitHub-Flavored Markdown — headings, bold/italic, tables, task lists, strikethrough, blockquotes, and more rendered flawlessly
  • Syntax-highlighted code blocks — 180+ languages powered by highlight.js with GitHub's signature colour themes
  • Smart typography — curly quotes, em-dashes, and ellipses automatically applied
Dark & Light Themes
  • Toggle between light and dark mode with a single click — or press D
  • GitHub-accurate colour palettes for both themes, including syntax highlighting
  • Your preference is remembered across sessions

Is Markdown Viewer Pro 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.

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

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.

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