One of the challenges creating a browser extension like Glances is that it has to work within every single website, and since every website is created differently, it can be hard to support every website.
If you find the Glancey stamp does not work consistently on a website you use often, please reach out to us and let us know. We may be able to update the browser extension and add support for the website.
In the meantime, try clicking the Glances widget icon in the bottom right corner and selecting the person you want to view from the dropdown.
If you still have any other issues, please reach out to us at support@glances.com so we can troubleshoot further.
