Hi Nick, where is Yahoo showing up now? For example: (1) At startup or in a new window (Ctrl+N), it takes over as home page (2) When opening a new tab (Ctrl+T) (3) When running a search from the address bar, it has replaced your preferred search engine (4) When running a search on a completely different site, results show up instead on Yahoo Very often, the problem starts with a new add-on. 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, private search, or Yahoo? Anything 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 are blocked from using the page or the page is blank/empty:''' You can re-check the page in Firefox's Safe/Troubleshoot Mode. In that mode, Firefox temporarily deactivates extensions, hardware acceleration, any userChrome.css/userContent.css files, and some other advanced features to help you assess whether these are causing the problem. You can restart Firefox in Safe/Troubleshoot Mode using either: * "3-bar" menu button > Help > Troubleshoot Mode... (before Fx88: Restart with Add-ons Disabled) * (menu bar) Help menu > Troubleshoot Mode... (before Fx88: Restart with Add-ons Disabled) and OK the restart. A small dialog should appear. Click the Open button (before Fx88: "Start in Safe Mode" button). '''''After cleaning out non-essential extensions:''''' You may need to clean up home page, new tab, and search settings. These articles should get you to the relevant parts of the Settings page: * [[How to set the home page]] * [[Change your default search settings in Firefox]] Can you regain control of your Firefox experience?
