I installed in Firefox and followed the instructions to modify permissions but NEVER got it to work. Firefox would always display local files as plain text, never rendered. Perhaps a Firefox issue, perhaps some tricky configuration issue, but for me, wasted time trying to make it work. Removed the extension.

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!

So good. For anyone new:

- for rendering local files, follow instructions on the project's GitHub page github.com/simov/markdown-viewer

- for rendering files from internet, follow github.com/simov/markdown-viewer/blob/main/firefox.md

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.
