I tried the official Todoist extension, Better Todoist and this extension. This one fits my needs of sending GitHub issues to Todoist the best. I can highlight the piece of text and the right click and send it to Todoist. It is still not perfect but good enough for my needs. I can imagine using it more in the future. The "highlighted text to task" feature seems very handy.

I'm not seeing any context menu to send the page to Todoist. Are you doing phishing? I have to re-sign my Todoist for security and will remove this extension before proven to be working properly.
