Office 365: Mail page blank in Firefox, shows �Continue� on tab

Technology

Blogging this one from a colleague in case anyone else hits the same symptoms.

User was logging�into Mail in Office 365 using Firefox.

The page was completely blank.

Instead of the browser tab label saying Mail � Username it just said CONTINUE.

Worked correctly in Internet Explorer.

Could access the same Office 365 account correctly from another computer on the network using Firefox.

Troubleshooting things that didn�t work:

  • Opening Firefox in safe mode
  • Resetting Firefox to defaults
  • Clearing cache
  • Deleting cookies
  • Removing save password

The fix was to create a new Firefox user profile:

  • Sync Firefox current user profile settings to the internet
  • Create a new user profile, using the Firefox user profile tool
  • Sync old settings to new profile

All settings should come across, except pinned tabs.

Thanks Brian Messenger for sharing your wisdom with me!

P.S.��Looks like the error was a Java problem. Java was installed & active. In fact, all java versions had�been removed, the latest reinstalled and verified, but the Firefox console was showing some java commands in a recursive loop.
