Firefox extension: Secure Or Not

When you visit some secure web pages, you sometimes see this alert message:
And you would wonder what information on the page is unencrypted.

This Firefox extension will answer the question. It shows whether the links on a webpage are https links or http.

After installation, a "Secure Or Not" item is added to the context menu -- usually you can right-click the webpage or use the menu key on your keyboard to show the context menu.

When you select it on the context menu, the http links on the webpage would be bordered by red dashed lines; and the https links on the webpage would be bordered by green dashed lines. Similarly, forms to be submitted insecurely would be bordered by red dashed lines; and forms to be submitted securely would be bordered by green dashed lines.

Isn't that simple?

(Since version 1.1) Images and iframes are also shown whether they are transferred in secure communication or not. Sometimes an image can have a link to another page, it could then be bordered twice. In such a case, there could be a conflict of the color of the borders. For example, if the image is stored in an insecure location but the link points to a secure URL, the image could have both a green and red border.

(Since version 1.1) You can also press the shortcut keys Ctrl-Shift-S to execute the extension.

Download and install it here:

You will need to restart Firefox browser after the installation.


• Ignore links (since version 1.1): if it is checked, the secure status of the links on the page are not shown. Because in a secure page, although a link can point to another insecure page, the link itself is transferred in a secure channel. Usually a browser considers the content of the page as secure even there are links pointing to insecure pages. We allow you to select this option so the extension will not show those links as insecure. That would be consistent with the browser's behavior. By default, the option is not checked.

Hi Guys :)

This looks a good idea; thanks for taking the trouble to code it.

Just one thing, and I'm probably being blind or dim here, but I can't seem to see any link for the Source Code anywhere..

Can you point us in the right direction. Cheers. :)
