I have set up latest version firefox V42.0 as enterprise wide software running on windows.

I want to have the Markdown Viewer add-in ([email protected]) available and active for all users.

I have used the CCK2 add-in ([email protected]) to specify all the details. Everything works fine for my account when accessing firefox, but new users recieve the following message

  • * *

[Exception... "AddonManager is not initialized" nsresult: "0xc1f30001 (NS_ERROR_NOT_INITIALIZED)" location: "JS frame :: resource://gre/modules/AddonManager.jsm :: AMI_getInstallForURL :: line 1897" data: no]

AMI_getInstallForURL@resource://gre/modules/AddonManager.jsm:1897:1 AM_getInstallForURL@resource://gre/modules/AddonManager.jsm:3014:1 observe@resource://cck2/CCK2.jsm:847:15

The add-in isn't copied from the firefox install folder (which is a read-only mapped drive on an external server) to %APPDATA%\Mozilla\Firefox\Profiles.


Question: What should I be doing so that new users can use firefox and apart from the "importing settings" type dialog everything is seamless and the markdown viewer add-on works?

Let's start here first,

It is possible that there is a problem with the file(s) that store the extensions registry.

Delete the extensions.* files (e.g. extensions.json, extensions.sqlite, extensions.ini) and compatibility.ini in the Firefox profile folder to reset the extensions registry.

New files will be created when required.

See "Corrupt extension files":


If you see disabled or not compatible extensions in "Firefox/Tools > Add-ons > Extensions" then click the Tools button at the left end of the Search bar to check if there is a compatibility update available.

If this hasn't helped then also delete possible addons.json and addons.sqlite files.

You can also check for problems with preferences.
