Zoho PageSense relies on third-party cookies and script calls to track visitor behaviour on your website. Increasingly, these cookies and requests are blocked by corporate firewalls, ad blockers, and built-in browser tracking protections such as Safari's Intelligent Tracking Prevention or Chrome's phase-out of third-party cookies. When PageSense's script calls are blocked without being handled gracefully, the resulting unhandled JavaScript errors can stall page rendering or crash the site entirely for affected visitors.
Many corporate networks and browsers now actively reject connections to third-party analytics and tracking domains. If your website code calls PageSense functions without first checking whether the script loaded successfully, a blocked request can throw an error that halts further JavaScript execution on the page, taking other functionality down with it.
You do not necessarily have to abandon PageSense altogether. If you would rather keep it running while removing the crash risk, wrap the tracking script so that blocked network calls fail gracefully instead of breaking the page.
Make sure the Zoho PageSense snippet in your HTML <head> uses the non-blocking async attribute. This way, if a firewall drops the request, the browser continues parsing the rest of the DOM and running your other JavaScript as normal, rather than waiting on PageSense.
If your site calls PageSense functions elsewhere in its code, for example custom event tracking such as pagesense.track(), wrap those calls in a try...catch block, or check that the object exists before calling it:
If corporate firewalls or strict browser settings are rejecting PageSense on the basis of your CSP headers, add Zoho's origins to your website's policy so the browser does not kill the script thread:
