The extension requires the following permission from you for working.
contextMenus: to show option when right-clicking.activeTab: to be able to access content on page.
Copying to clipboard might not work in some of the following scenarios:
- You are on an insecure page (URL starts with
http://instead ofhttps://). - You have not interacted with the page yet.
These are a result of the software design decisions made to protect the user from bad actors. The MDN article section "Security Considerations" lists what these limitations are and why they exist.
More info can be found on MDN about User Activation and Secure Contexts.
Web pages sometimes embed content from other page using an iframe. Due to security considerations around accessing and modifying clipboard (see section above), this extension doesn't work if you try to copy text from inside these frames.
When copying links and images, Chrome doesn’t let you extract images alt text or anchors text content to be used in Markdown, instead the links themselves are used as link title. Firefox doesn’t have this limitation.
