Hello,
I cannot login to Atlassian website (bitbucket, wiki, jira) using Firefox 59.* I am not sure it is problem with Version of FF but just for the record ... The webserver says:
Something has gone wrong

try again using the button below (without refreshing the page):
But I allowed third-party cookies to be accepted. Can anyone hint me how can I investigate it ?
