" ... /us/en/ ... " in order to reach the English language website? 

Why has my otherwise serviceable Firefox for Android suddenly begun redirecting my input of "nnnnn.com" to "https://www.nnnnn.com/sa/ar/Home.page.com" ; forcing me to edit the url to include " ... /us/en/ ... " in order to reach the English language website? I occasionally research Arabic language websites and those are rarely if ever Saudi Arabian as the redirect imposes. Update: Troubleshooting I did on Firefox Android shows that my issue is only in Private Mode. Typing the affected URL in regular mode gets me to the correct US English home page with no redirect to the Arabian version.
