Great extension.
BTW, Is there a way that i can replace '..' with any other character as the parent path？

Does not register the .md file extension with the browser, so any attempt to open a markdown file leads to the Firefox "open with..." dialog. An alternative would be to add an "Open" button to this extension's panel, and have it properly open markdown files inside the browser pane. Otherwise this extension does not work at all because it is totally incapable of opening any markdown file.

Awesome, that's what I'm looking for :-)

Just after installation in Firefox, Windows 10 Home, I had a problem to find application icon on Firefox taskbar. I've asked for advice sending support e-mail. The feedback was immediate. The application works great even with `mermaid` Markdown extension. Happy to use it. Thank you for your effort!

Thanks a lot for this great extension.

Very good!
I have installed it on Firefox and Edge ,it well !

On Firefox, you need to do an extra security step before you can use it(Firefox require).

And before use it, you should uninstall any other markdown extensions.

Finally, thanks agian to the author Simov.

Works great if you configure it properly on Linux using this guide: https://github.com/simov/markdown-viewer/blob/main/firefox.md. If you using Ubuntu probably you have the snap version. In that case in about:config (following the steps on the previous URL) on Firefox be sure to put the full path of the mime file avoid using ~ character. And after that if the addon is not rendering properly the md files, then go to the advanced options of the addon and give the necessary permissions on file access and site access. The addon is great but this process complicate things. However it is worth it!

Does not work in ubuntu 22. Extension reports that it can't read (or change) data from local files

Works great after this workaround: https://github.com/Cimbali/markdown-viewer#support-for-local-files-on-linux

It doesn't support tables!

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.
