I have check this. Since several days, like the last Update of Google chrome to the latest Version, i get this error, too!
Error: Unchecked runtime.lastError: The message port closed before a response was received.
I got this Error on every Sites, which you visit! And the Counter doesn't stop.
I have check this and find following:
1.) Google says, this will happen, because Google Crhome does not allow Croos-Origin.
I have reinstall, check PCs and so... but
2.) Only what will help, is to uninstall the extension "Kaspersky Protection".
3.) You have to check this. Uninstall the Extension: Everything fine again! (Only - no protection...)
4.) So, I think, the Developer-Area has to check this... maybe together with google, because i find every days, more and more People, who got this error. And, not forgot: Noteverybody looks in the console or knows what is "Console" in Crhome...
At Last: Only in Google - Chrome - this happen and only after the last Version ( Since Version: 99 / 100...)
@ the moment:
Deinstall the Extension: "kaspersky Protection" --> No Problem.
