How do I fix this?

Hi

The browserconfig.properties file was used in older Firefox versions to set a localized homepage. This has been changed in Firefox 63 to have support for non-localized homepages, so seeing a reference to this file is likely a leftover from an older Firefox version. You can check the browser.startup.homepage pref on the about:config page and reset this pref to the default value.

You can open the about:config page via the location/address bar. You can click the button to "Accept the Risk and Continue".
