Google translate is not working

You need to turn off extension guard in order to install this extension. Don’t know why since it’s a perfectly good and secure extension.

No, you don’t need to disable Extension guard in order to install extension from Google Chrome store, the warning appears because the Google Translate ext. is not whitelisted.
You can just proceed with checking ‘I understand the risks’ and clicking button ‘Install anyway’.

My Error Josef,
I missed the option to accept the risk.
