Try disabling the Ask Toolbar, then restarting Firefox. If that does not work, you may need to try Firefox Safe Mode * You may need to use '''Safe Mode''' to locate the problem: http://kb.mozillazine.org/Safe_Mode *Firefox Safe Mode is a diagnostic mode that disables Extensions and some other features of Firefox. If you are using a theme, switch to the DEFAULT theme: Tools > Add-ons > Themes '''<u>before</u>''' starting Safe Mode. When entering Safe Mode, do not check any items on the entry window, just click "Continue in Safe Mode". Test to see if the problem you are experiencing is corrected. * If the problem does not occur in Safe-mode then disable all of your Extensions and Plug-ins and then try to find which is causing it by enabling '''<u>one at a time</u>''' until the problem reappears. '''<u>You MUST close and restart Firefox after EACH change</u>''' via File > Restart Firefox (on Mac: Firefox > Quit). You can use "Disable all add-ons" on the Safe mode start window. * See the following for more information ** http://support.mozilla.com/en-US/kb/Troubleshooting+extensions+and+themes ** http://support.mozilla.com/en-US/kb/Troubleshooting+plugins ** http://support.mozilla.com/en-US/kb/Basic+Troubleshooting ----------------------------- <br /> '''Other issues that need your attention''' The information submitted with your question indicates that you have out of date plugins with known security and stability issues that should be updated.
