We do have Google Ads on some of our pages and they track all sorts of things. If you do not wish to be tracked by them but wish session management to work properly here, most browsers have a way of accepting cookies from the visited site but not third parties.
In Firefox, go into Preferences, Select the Privacy Tab, then where it says, “Firefox will: Remember History”, that is a pull-down bar. Select Use Custom Settings for History.
Then under History, leave accept cookies from sites checked, but change accept third party cookies to “Never”.
That setting will allow sessions to work properly here and still prevent your activities on the Internet from being tracked by cookies.
