@ShadowJonathan @simon I was on google.com. Not signed in, though; maybe it only works if you're signed in to a Google account? The error message is: Uncaught TypeError: Cannot read properties of undefined (reading 'sendMessage') at <anonymous>:1:16
That's from the console I get with from "Inspect" in the context menu, then Console. If I use the hamburger menu More Tools->Developer Tools console, I get: Uncaught TypeError: chrome.runtime.sendMessage is not a function at <anonymous>:1:16

Funny.
I saw the same error, at first.
Turns out I had to be literally be on google.com, not a blank tab that shows a google search box. I'm not signed in to anything and it worked.
