MDPreview

MDPreview is browser extension to preview Markdown files locally or on the web. It is forked from GitHub Flavored Markdown.

Features

Compared to GitHub Flavored Markdown v0.0.6, MDPreview for Chrome 0.1 made the following changes:

Added a Windows registry file md.reg to tell what the MIME type of .md file is.
Dropped type support for .mdown .markdown, added type support for text/vnd.daringfireball.markdown
Don't watch opened local file by default.
p.s. Users can set whether or not to watch opened local file in future release.
Support physical A4 21cm-width to preview content.
p.s. you need to customize relative DPI ratio according to your monitor in page.css. in my case it's 1.4709583133562356, a.k.a. Math.sqrt(1920*1920+1080*1080)/15.6/96.

Open Chrome, navigate to chrome://extensions/, enable developer mode and drop this folder into the Chrome Extensions page.
Open a .md file with Chrome locally, or visit any web .md resource with one of MIME types text/plain text/markdown text/x-markdown text/vnd.daringfireball.markdown.

Open Firefox, navigate to about:debugging, click "Load temporary add-ons" and select manifest.json.
Open a .md file with Firefox locally, or visit any web .md resource with one of MIME types text/plain text/markdown text/x-markdown text/vnd.daringfireball.markdown.
