End users that use Firefox, Chrome, Edge, or Internet Explorer cannot access any isolated website when Symantec Web Isolation has been deployed.
The browser displays one of the following, instead of the isolated page:

Browser privacy extensions will commonly come with an option to disable third-party cookies / localstorage access, or to enable it on a whitelisted URL basis. When you see these issues, try to test with all browser extensions disabled. Assuming that works, you can re-enable one at a time until you know which extension is configured to block them, and then look into its specific settings.
