Many links shared by correspondents over or into other apps have recently stopped opening. Typically a blank white page. Often share.google links, clicked from whatsapp, open firefox then give this blank white page, presumably this is Google's attempt at tracking without cookies & FF is blocking them. For example: clicking this from whatsapp https://share.google/8XIPjfzcE6gtZzfsi opens just fine if pasted into chrome but that's not my default browser.
