About SameSite cookies and Chrome:

With recent changes to Google Chrome, cookies are now defaulted to SameSite=Lax. This may cause issues when attempting to send cookies to an external site.

This addon can resolve issues where offsite cookies are required, such as offsite payment gateways and tracking that requires cross-site cookies.

Note that not all browsers are compatible with SameSite=None. This addon will handle those that are not compatible and leave the parameter blank. https://www.chromium.org/updates/same-site/incompatible-clients
