When I open my Yahoo mail account, it comes up with lines between every entry. When I try to send a new message, the dialogue box is incomplete. The tool bar above the message box is empty so I cannot change the font or font size, etc.

This problem does not occur when I open my Yahoo mail account in Internet Explorer. Because of it, I cannot use Firefox to access my Yahoo mail.

Start Firefox in Diagnose Firefox issues using Troubleshoot Mode to check if one of the add-ons is causing the problem (switch to the DEFAULT theme: Tools > Add-ons > Themes).
