## Get the certificate to the browser

The easiest way to get the certificate to the browser is to use [the web
app](@!urlTo("webapp.html")!@). If this fails, do the following:


<ol class="tlist">
    <li> If needed, copy the ~/.mitmproxy/mitmproxy-ca-cert.pem file to the target. </li>

    <li>Open preferences, click on "Advanced", then select"Certificates":
        <img src="@!urlTo('firefox3.jpg')!@"/>
    </li>

    <li> Click "View Certificates", "Import", and select the certificate file: 
        <img src="@!urlTo('firefox3-import.jpg')!@"/>
    </li>

</ol>


## Installing the certificate

<ol class="tlist">
    <li>Tick "Trust this CA to identify web sites", and click "Ok":
        <img src="@!urlTo('firefox3-trust.jpg')!@"/>
    </li>

    <li> You should now see the mitmproxy certificate listed in the Authorities
    tab.</li>
</ol>
