There has been some scuttlebutt on the net regarding an issue that started with the release of Firefox 45.0 on March 8. The issue is that while using Firefox 45.0 to process email at Outlook or Hotmail, the user can not create a new email. When the "NEW+" button is clicked to write a new email, nothing happens. For the time being, if anyone here is using Firefox - you may wish to keep Version 43.0.0 or Version 43.0.1 until such time as version 45.o is repaired. Version 44.0 and it's sub versions may also have the glitch, so caution is suggested.
