Also, how are you trying to open a new tab? Ctrl-T? + in the tab bar? Right click, New tab or from the File menu?

  1. In the Tools menu select Add-ons to open the add-ons manager.
  2. In the Add-ons manager select the Extensions panel
  3. In the list of Extensions click on Ask Toolbar, then click the Uninstall button
  4. Restart Firefox and the Ask toolbar will be uninstalled.
