+This error can also be caused by browser privacy features such as Enhanced Tracking Protection (ETP) in Firefox or LibreWolf:
+
+* Firefox’s Enhanced Tracking Protection (ETP) can cause this error, especially in Strict mode. Add your codespace URL as an exception or turn ETP off.
+* LibreWolf, however, does not have the ability to turn off ETP. LibreWolf also forces Strict mode on ETP as well, meaning you must add it as an exception. To add exceptions, follow [Mozilla's guide](https://support.mozilla.org/en-US/kb/manage-enhanced-tracking-protection-exceptions).
