After upgrading to 50.0.2 I can't access my member page on ancestry.com The ancestry web page loads normally, but when I sign in and press enter, I get the message that the requested URL could not be found, please make sure that you entered it correctly. It does load normally with microsoft edge, so it is something in the latest release of firefox that seems to be blocking it.

If you use a bookmark or use a link that has specific GET data appended to the link or a page that has been requested by sending a form with POST data to open a specific page on the server then try to navigate to that page starting with the main page or the sign in page in case this bookmark/link is currently broken. If you use a bookmark then try to navigate to that page starting with the main page or the sign in page in case there is a problem with this bookmark.

Best is to avoid bookmarking a specific page that was requested by sending POST data in a (hidden) form or bookmarking a page that has GET data appended to the URL (?xxx=xxx) or links to a specific sub domain (xx##.example.com) in case load balancing is used as such a link can easily get broken in case of changes on the server.
