Firefox will not open due to "Firefox can’t find the file at jar:file:///Applications/Firefox.app/Contents/Resources/browser/omni.ja!/chrome/en-US/locale/branding/browserconfig.properties." Re-trying does not fix. Delete and reload does not fix. Need an answer. Jim

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 via the right-click context menu to the default value.

You can open the about:config page via the location/address bar. You can accept the warning and click "I accept the risk!" to continue.
