Google News
2021Jun14 In Firefox 89.0, Google News main page 'Headlines' only loads 'Top Stories'. All other categories, e.g., U.S., Business, Entertainment, Technology, Sports, etc., do not appear as categories. They do appear on left hand column of Main page but when selected they display message 'Uh-oh, something went wrong. Please try again.' with a Reload link. Reload opens category but has no effect on what displays on Main page 'Headlines'. This problem does NOT exist when using Chrome - Google News works as usual in Chrome.
