Does what it says on the tin for the most part, doesn't display tables from Reddit correctly though.

My first impression was that it was useless, because it states file:// URLs aren't supported. The docs on GitHub talk mainly about Chrome and the video has no sound, so I didn't find the workaround that somebody else posted in a comment. Here's the fix: https://superuser.com/questions/696361/how-to-get-the-markdown-viewer-addon-of-firefox-to-work-on-linux/1175837#1175837

The fact that this isn't clear in the instructions seems a pretty scathing oversight.

Anyhow, once I added the MIME type, it started working pretty well.

It lacked a bit of detail to set the Markdown title to the tab's title when the file was loaded.

It's an excellant addon,but the support of printing page is poor .the page rendered by this plugin can not be printed completely.

这个扩展很好用，但是对打印的支持不尽如人意。这个插件渲染的页面无法被完整地打印。

Great, but Table of Contents sorely needs a dark option.

The same problem with the plugin on KDE. In spite of the [MIME solution by Firefox user 15126385](https://cup.aihedy.com/en-US/firefox/addon/markdown-viewer-chrome/reviews/1453572/) works perfectly, I have to refresh the page or change any of settings to see the content instead of blank page.

Plugin v. 3.8
Firefox v. 74.0

P.S. That solution for KDE should have appearance in the Documentation.

Good, but it doesn't correctly interpret code blocks for python
