This extension makes mailto: links actually useful again by opening the real Gmail compose window. When you click on any mailto: link, Gmailto will:

Open the official Gmail website in a new tab (just like if you opened it yourself)
Wait for Gmail to fully load and then open a real compose window, not some huge draft screen or fake editor
Automatically copy the recipient’s email address to your clipboard

Once the compose window appears, all you need to do is:

Right-click in the "To" field and choose Paste or just press Ctrl + V on your keyboard

That’s it! Now you can type your message and send it just like you normally would. Why doesn’t it paste the email automatically? Because Gmail’s own website prevents extensions from interacting with the input fields directly. This is a built-in security feature by Google. No addon can bypass this without using unsafe methods, which Gmailto does not do. Instead, Gmailto gives you the next best experience by copying the address for you, so pasting it is just one quick action away. Tips:

You can click multiple mailto links, each one opens in a new Gmail tab
Works perfectly with multiple Gmail accounts (just choose the right one in your browser)

Permissions: This extension asks for the following permissions so it can work smoothly:
