Suppress "Allow this installation" page

I'm trying to deploy an add-on to users in our organization.

I am copying the .xpi file to the users Firefox profile and in the extensions folder.

However, when launching Firefox, a page opens where you have to allow this installation.

Is there some way to suppress this page, or to force the install of this add-on?

I tried looking for an option on the about:config page, but I am yet to find anything. Perhaps I have missed something?

Thanks.

Sam.

You can try to set (lockPref()) extensions.autoDisableScopes to 0 (zero) to see if that helps.

Hello Sam, probably you can't install your extension because in firefox 43+ an extension must be signed to allowed installed in firefox.

Anyway you can change that, i hope, toggle the xpinstall.signatures.required to false in about:config and check it again.

from 47 firefox version and newest versions, Signing will served with no pref to turn off.

Thanks for getting back to me.

The add-on I am trying to install is signed by Mozilla.

I tried toggling that option in about:config, but nothing changes.

I am still receiving the "Allow this installation" page where the user has to check the checkbox and to allow the installation of the add-on.

Thanks.

Hello,

I am still receiving the "Allow this installation" page using the registry method.

I can install the add-on for a new Firefox user profile(however it is disabled for some reason). But the page still displays for existing Firefox profiles.

Thanks.

I found this, but don't understand any of it.

http://kb.mozillazine.org/About:config_entries

Extensions.

extensions. autoDisableScopes

Integer

"Extension scopes" where newly installed addons are disabled by default (Gecko 7 and later since 2011-06-28, see bug 666437). This is an additive bit field:

1 = addons found in this profile (this bit is probably masked off) 2 = addons applying to all profiles of this user 4 = addons applying to all users of this application 8 = addons (e.g. plug-ins) applying to anyone on this computer

Default varies among versions: Undefined (no disabling, as with 0), 10 (all except app-global and user-profile), 15 (all, but does not apply to some specific locations such as IIUC installdir/extensions/ and profiledir/extensions/)

Hello,

Thanks for getting back to me.

I can confirm setting the following Pref works successfully:

lockPref("extensions.autoDisableScopes", 0);

Thanks very much for your help.
