Annoying pop-up "There is no application set to open the URL chrome-extension...."
When my Mac restarts I get repeated pop-ups with messages: "There is no application set to open the URL chrome-extension://ekhagklcjbdpajgpjgmbionohlpdbjgc/translateSandbox/translateSandbox.html."
I am not running Chrome, and have deleted the application. I have also deleted all the extensions to Chrome that I can find.
Still this pop-up comes. Where does it come from and how do I stop it happening?
Is this malware?
I'm on a MacBookPro running MacOS "15.3.1 (24D70)".
I've seen other threads with the same question, going back to 2021. But there so far seems to be no answer.
