Markdown Viewer Webext

Markdown Viewer Webext is a powerful browser extension designed to render markdown documents seamlessly within your browser. It detects markdown files based on URL extensions like .md and .markdown and converts plain text markdown syntax into beautifully formatted HTML. Whether you're viewing files online or locally, the extension supports rendering with a simple button click or optionally automatic rendering.

Key features include dark mode support, multiple styling options including a GitHub-like look, customizable CSS, and syntax extensions such as checkboxes, footnotes, LaTeX, mermaid.js diagrams, and emojis. It ensures security by rendering inside a sandboxed iframe and respects website Content-Security-Policy headers. Users can also download rendered markdown as static HTML or link back to the original source. The extension requires minimal permissions and works efficiently without compromising privacy.
