This is in the address bar when I open a new window; chrome://branding/locale/browserconfig.properties This is the message I get and have to open a new tab: File not found

Firefox can’t find the file at jar:file:///C:/Program Files/Mozilla Firefox/browser/omni.ja!/chrome/en-US/locale/branding/browserconfig.properties. 

   Check the file name for capitalization or other typing errors.
   Check to see if the file was moved, renamed or deleted.

Why do I keep getting this instead of a fresh new window? It is annoying to have to open a new tab after a new window.

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 browser.startup.homepage 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. On the warning page, you can click "Accept the Risk and Continue" to open about:config.
