I have installed an add-on using a GPO.
However, after upgrading to Firefox 68, my add-on is getting an installation error.
Is it impossible to install by GPO on Firefox 68? If not, why is not it installed?
The following is the part I checked about by connecting to about:policies.
Installation via download, not GPO, is installed normally, below is the installation link.
In the case of GPO installation, my add-on as well as other add-ons are not installed.
Please check the issue.
