I'm trying to auto enable 2 extensions for my users, and after hours on the issue, I cannot find any fix.

We are using: ESR 91.4 32 bits

I've tried to use: - Group Policy -> ExtensionSettings {

 "policies": {
   "ExtensionSettings": {

"": { "installation_mode": "force_installed", "install_url": "file:///c:/Program Files (x86)/Ivanti/Workspace Control/Data/DBCache/Resources/custom_resources/Logiciels/Mozilla/extensions/" }, "": { "installation_mode": "force_installed", "install_url": "" } } } }

- and Registry HKCU\Software\Policies\Mozilla\Firefox -> ExtensionSettings (REG_MULTI_SZ): { "": { "installation_mode": "force_installed", "install_url": "file:///c:/Program Files (x86)/Ivanti/Workspace Control/Data/DBCache/Resources/custom_resources/Logiciels/Mozilla/extensions/" }, "": { "installation_mode": "force_installed", "install_url": "" } }

-> HKCU\Software\Policies\Mozilla\Firefox\Extensions\Install 1 (REG_SZ): c:\Program Files (x86)\Ivanti\Workspace Control\Data\DBCache\Resources\custom_resources\Logiciels\Mozilla\extensions\ 2 (REG_SZ):

The result is: extension are installed, but always disabled. I have to manually enable them.

Would you have any idea?

thanks for help

Is it possible these extensions were disabled in the past? Can you try a new profile?

Hi Mike,

All the testing I did always were new profile.

For each test, I delete the actual profile, create new one, and check if the addons are auto enabled.

OK, so I see two issues here.

1. The first extension appears to be a third party installed extension. Do you see the extension referenced at:




in the registry?

For this to work properly, you need to make sure the extension is not being installed as a third party extension and is only installed via policy.

2. For the second extension, the ID is wrong. It should be {2dd2655f-1b39-42e3-a286-6cc0039dbdea} instead of
