Hi all,

we are using Mozilla Firefox ESR in our enterprise environment.

Is there a documentation which URL's Firefox uses when (Mozilla Maintenance Service) when it tries to update his version ?

We have tried with following URL's on our Firewall:

aus.mozilla.org aus2.mozilla.org aus3.mozilla.org aus4.mozilla.org aus5.mozilla.org download.cdn.mozilla.net archive.mozilla.org ftp.mozilla.org

It is finding the new version, but when trying to download the update it fails.

Thank you for any help on this case.

Those URLs should be enough I think.

You can set the preference app.update.log to true in about:config and then see what the errors are on the JS console.

Hi Mike,

thank you for the reply.

Is there no official document or manual which describes the required URLs for Firefox ?

When i take a look on the Google Chrome Browser, those URL's are listed. https://support.google.com/chrome/a/answer/6350036?hl=en&visit_id=637920025843684779-2168098556&rd=1#zippy=%2Cwhat-urls-are-used-for-chrome-browser-updates

Same is also listed for the Edge Browser. https://docs.microsoft.com/en-us/deployedge/microsoft-edge-security-endpoints


If i am starting the console i found another URL where the Moziall Maintenance Serivcde tries to download.

download.mozilla.org

Thank you
