Error in Snowflake debug console, caused by a line in vapi-background.js
in uMatrix:
{{{Unchecked lastError value: Error: First-Party Isolation is enabled, but
the required 'firstPartyDomain' attribute was not set.}}}
The uMatrix setting causing this error is:
{{{Spoof HTTP referrer string of third-party requests}}}, when set to
true.
This is a bug either in Snowflake, or uMatrix.
