Hi there, the addon is available to improve the accuracy of FocusMe reading the current URL. A lot of the time, the difference having it and not having it might be negligible but that does not mean it's not working. The app has protection under the settings to block browsers when no URL is detected. This feature protects against the addon being removed in the case of it being the only working method to get the URL.

Please will you reach out to our support so we can clarify this further? https://focusme.com/support/

Thanks
