On Microsoft.com it shows me logged in, but on Bing.com the page just refreshes and doesn't sign me in. Only happens on Firefox, other browsers don't seem to have this problem.

Chosen solution

Make sure you are not blocking content.

Start Firefox in Safe Mode {web link}

A small dialog should appear. Click Start In Safe Mode (not Refresh). Is the problem still there?


One issue that seems more common lately is Firefox's Content Blocking. When it is blocking content in a page, a shield icon will appear at the left end of the address bar next to the padlock icon. This article has more info on managing this feature:
