Enable third-party cookies

Browser Isolation currently depends on third-party cookies to maintain a short-lived session between your local browser and the remote isolated browser.

Each web browser treats third-party cookies differently, and some browsers (for example, Chrome and Firefox) may only present this error while incognito / private browsing mode is active. Depending on how your browser is configured, you may need to enable third-party cookies to access isolated websites.

Follow these instructions to enable third-party cookies in your browser:

  3. Scroll down to Privacy and security, click Cookies and other site data.
  4. Click See all cookies and site data > Remove all.
  5. Confirm by clicking Clear all.

Firefox (Private Browsing mode)
