Cannot install add ons

Trying to install add-ons, I get "An unexpected error occurred during installation."

I checked the about:policies#active and InstallAddonsPermission is false.

The Firefox is portable and I was able to install add-ons in the past.

It is a managed computer, and this is why I use the portable version. I was under the impression that the portable version is not subjected to a policy since the software is not being installed.
