Hi,

Please check if this happens in Safe Mode. Safe Mode is a temporary diagnostic feature and you can exit and start Firefox normally again. The installed Extensions, themes (Appearance) and Plugins are disabled in safe mode.

Both the Yahoo! Toolbar extension and the Babylon extension have been reported to cause an issue like that. Disable or uninstall those add-ons.
