Browser and session compatibility in FXM


An overview of how FXM tracks contacts on different browsers.

Because of the differences between browsers, FXM cannot always track contacts with the same ID across multiple sites.

The following tables list the currently supported options:


If the external site and the Sitecore site are hosted on different domains:

  • For Chrome and Firefox – FXM can successfully track the same contact across both websites.

  • For Safari and iOS or any version of IE – FXM assigns each contact a unique contact ID per website.
