Is Markdown Here Safe? — Extension Safety Profile

The extension requests permissions for activeTab, contextMenus, storage, and scripting. This allows it to read and modify content on the current page only when you click its toolbar button or right-click context menu item, save your preferences locally, and inject its conversion script. For a Markdown formatting tool that transforms text in input fields or rich-text editors, this permission set is normal and expected—it gains no persistent background access or network capabilities.

General-purpose formatting extensions typically pose low inherent risk, but a careful user should be aware that any tool with activeTab and scripting can potentially read sensitive visible text from the active page at the moment of use. As a precaution, avoid activating it on pages containing confidential data, and verify you have installed the genuine extension from a trusted author, since malicious clones could repackage similar functionality.

The safety score's strongest dimension is Data & Privacy (100%), reflecting the developer’s declared commitments not to sell user data or use it for unrelated purposes. The weakest dimension, Maintenance & Ownership (30%), indicates a lower confidence score in the extension's long-term upkeep or publisher track record—despite a recent 2025 update—so users may want to weigh this when depending on the tool.
