# Install root certificates

Here is the procedure to install root certificates.

{% hint style="info" %}
Firefox does not trust the same certificates as Windows and a setting must be applied to enable this.

Please consult [Mozilla's knowledge base article](https://support.mozilla.org/en-US/kb/setting-certificate-authorities-firefox).
{% endhint %}

{% tabs %}
{% tab title="Windows" %}

1. Open the Microsoft Management Console by searching for ***MMC*** in the ***Start*** menu. Another way is to press the <kbd>Windows</kbd>+<kbd>R</kbd> keys on your keyboard and, in the ***Run*** window, search for ***MMC***.
2. Select ***File – Add/Remove Snap-in***.
3. In the ***Available snap-ins*** box, select ***Certificates***.

5. In the wizard, select ***Computer Account***, then click ***Next***.

9. In the ***Logical Store Name*** box, right-click ***Trusted Root Certification Authorities*** and select ***All Tasks – Import***.
10. Follow the instructions in the ***Certificate Import Wizard*** and provide the certificate file you have.
