add extension to chrome premanently

Hello everyone

I am working with a portable google chrome to make tests in a laboratory. And I have a problem that I still can not solve. when adding an extension to the portable, it works fine but when changing the pc device the extensions are deleted.

I was reviewing the forum but I have not been able to find any solution.

A possible solution would be to login with a google account in the browser, in this way the extensions would be integrated but for the activity that I must perform this option is not viable.

In short, my problem is installing permanent extensions the google chrome portable.

Attentive to your answers. regards
