Sorry to hear about your search getting hijacked. Usually, it's caused by an add-on, either a new one that was installed recently or an old one that updated recently. Does Firefox mention any extensions being involved with your search engine setting when you check the Options page, Search panel? You can view, disable, and often remove unwanted or unknown extensions on the Add-ons page. Either: * Ctrl+Shift+a (Mac: Command+Shift+a) * "3-bar" menu button (or Tools menu) > Add-ons * type or paste '''about:addons''' in the address bar and press Enter/Return In the left column of the Add-ons page, click Extensions. On the right side, find the "Manage Your Extensions" heading. ''If there is at least one extension before the next heading -- "Recommended Extensions" -- please continue:'' Then cast a critical eye over the list below that heading. Any extensions Firefox installs for built-in features are hidden from this page, so everything listed here is your choice (and your responsibility) to manage. Anything that mentions search, privacy, looks suspicious or that you just do not remember installing or why? If in doubt, disable (or remove). For your privacy and security, don't let mystery programs linger here. ''If you cannot access your extensions list -- blank or blocked page:'' Some users report needing to restart Firefox in its Safe Mode before they can manage extensions. Could you test in Firefox's Safe Mode? You can restart Firefox in Safe Mode using either: * "3-bar" menu button > "?" Help button > Restart with Add-ons Disabled * (menu bar) Help menu > Restart with Add-ons Disabled and OK the restart. A small dialog should appear. Click "Start in Safe Mode" (''not'' Refresh). Then hopefully you can finish the job. Finally, to clean up settings that might be affected: * [[Change your default search settings in Firefox]] * [[How to set the home page]] Success?
