Is Markdown Here safe?

Clean risk

Markdown Here stores a hidden base64 copy of the original draft in the page when it renders Markdown.

When you activate rendering in a compose box or editor, the extension replaces the selected Markdown with HTML and embeds the original content in an invisible div's title attribute so it can later unrender it. If TeX rendering is enabled, formula text is inserted into CodeCogs image URLs.

Shared hosts - 2 hostnames

Hostnames hardcoded in this extension that few other listings call. That can mean one operator behind both, and it can equally mean a small shared vendor, so it is context rather than a conclusion. Hosts that many listings call are left out: they are services, not connections.

Where it sends data
