Are you sure you don't have kaspersky installed? From a quick google seems like other users with the issue had it installed.

ImportEnterpriseRoots instructs Firefox to trust not only its own set of SSL certificates, but the ones installed in the Windows Certificate Store. Can you trust that? I believe malware attacks the system certificate store way more often than Firefox's cert9.db file, but if you have malware on your system, that is a bigger issue than Firefox trusting a questionable website.

In a perfect world, though, you would control whether this setting is on or off.

Policies can be applied through the Windows Registry -- this is more typical in a business where an IT department manages your computer -- or through a file named policies.json in a specific folder. Since uninstall removed it, my guess is the latter, a file in the program folder. Here's how you can track it down:

Typically, on 64-bit Windows, Firefox installs in:

C:\Program Files\Mozilla Firefox

A policies.json file would be here if you have one:

C:\Program Files\Mozilla Firefox\distribution

You may need admin privileges to edit/delete the policies.json file. What you might want to try is editing it by removing its contents, then marking it Read Only to try to prevent whatever process is inserting it from restoring the original policy.

I have Never had Kaspersky installed.

Thanks but no luck. Look's like i'm done with Firefox for a while. Zen Or Waterfox will probably be my next stop. Thanks for trying.

You weren't able to find the file, or you weren't able to edit the file?

Was able to delete but the problem remained. Cannot remember how to edit. Will look at it. Thank you.

Hi - I have the same problem (ImportEnterpriseRoots), but I do not have the Distribution folder so there's nothing to delete or edit. I am using Norton 360 (v25.4.10068.1594). What is it about Kaspersky that can cause ImportEnterpriseRoots and can Norton do that also? Thanks

Are you running Windows? The other way that an Enterprise Policy can be applied is using a Group Policy in the Windows Registry. More info: Customize Firefox using Group Policy (Windows).
