Chrome Extension - EJAVASCRIPT - Extension Manifest V3

Hello,

For many days all my local Chrome extensions monitors have been failing due to constant “EJAVASCRIPT: Javascript selectors are not supported in extension Manifest V3” -error.

The same monitors in same browsers worked fine not long ago. My extension version has been automatically updated to 3.10.5.

Any help with this?

Thanks already in advance!

chrome has now disallowed apis to execute arbitrary javascript in content scripts. as a result, js selectors won’t work in modern chrome versions. please note that chrome had set a deadline for all extensions to migrate to manifest version 3 by june.

the desktop app and the firefox extension which doesn’t have any such deadline can still execute javascript.

I see, thank you for the explanation. I will adjust my system accordingly.
