You can block Yahoo as your default search engine in most browsers within seconds, but the method depends on which browser you use and what device you're on
Blocking Yahoo means removing it as your default search engine and preventing it from appearing in search bars. Most people do this because they prefer a different search engine, want to stop Yahoo from tracking their searches, or accidentally set it as default. The steps differ between Chrome, Firefox, Safari, and Edge, and you may need to handle mobile devices separately from your computer.
You do not need special software or technical knowledge. Each browser lets you change your default search engine in settings, and you can also remove Yahoo's toolbar or extension if you installed one. If Yahoo keeps returning as your default despite your changes, a browser hijacker may have installed itself — that requires a different fix.
Key Takeaways
- Blocking Yahoo as your default search engine takes under a minute in Chrome, Firefox, Safari, or Edge through the browser settings menu.
- If Yahoo keeps resetting itself as your default after you change it, a hijacker extension or program may be installed on your device.
- Removing Yahoo toolbars or extensions from your browser prevents Yahoo from appearing in your search bar even if you do not change your default engine.
- Mobile browsers like Chrome on Android and Safari on iPhone have separate search engine settings that you must change independently from your computer.
- Restarting your browser after making changes ensures the new default search engine takes effect immediately.
How to block Yahoo in Google Chrome
Open Chrome and click the three vertical dots in the top right corner. Select Settings, then click Search engine in the left menu. Under "Search engine used in the address bar," you will see a dropdown showing your current default. Click it and choose a different search engine — Google, Bing, DuckDuckGo, and others appear in the list. Yahoo will no longer be your default.
If Yahoo does not appear in the dropdown list but keeps showing up when you search, you may have a Yahoo extension installed. Click the puzzle piece icon in the top right of Chrome, find any Yahoo-related extension, click the three dots next to it, and select Remove from Chrome. Close and reopen Chrome to confirm the change.
How to block Yahoo in Mozilla Firefox
Open Firefox and click the three horizontal lines (hamburger menu) in the top right. Select Settings, then click Search in the left sidebar. Under "Default Search Engine," click the dropdown and choose Google, Bing, DuckDuckGo, or another option. Yahoo will be removed as your default immediately.
Check the "One-Click Search Engines" section below the default engine setting. If Yahoo appears there, click it and select the trash icon to remove it. This prevents Yahoo from appearing as a quick search option. If you installed a Yahoo toolbar, go to Extensions and themes in the left menu, find the Yahoo extension, and click Remove.
How to block Yahoo in Safari on Mac and iPhone
On a Mac, open Safari and click Safari in the top menu bar. Select Settings (or Preferences on older versions), then click the Search tab. Under "Search engine," click the dropdown and choose Google, Bing, DuckDuckGo, or another option. Yahoo will no longer be your default search engine.
On an iPhone or iPad, open Settings, scroll down and tap Safari, then tap Search Engine. Select a different search engine from the list. Safari on mobile devices maintains separate settings from your Mac, so you must change both if you use both devices. Restart Safari after making the change to ensure it takes effect.
How to block Yahoo in Microsoft Edge
Open Edge and click the three horizontal dots in the top right corner. Select Settings, then click Privacy, search, and services in the left menu. Scroll down to the "Search engine" section and click the dropdown under "Search engine used in the address bar." Choose Google, Bing, DuckDuckGo, or another option to replace Yahoo.
If you see Yahoo listed under "Search engines used in the address bar" as an option but not as your default, click the three dots next to it and select Delete to remove it entirely. Close and reopen Edge to confirm the new default is active.
What to do if Yahoo keeps returning as your default
If you change your default search engine but Yahoo reappears the next time you open your browser, a hijacker program or extension is likely resetting it. Start by checking your extensions again — go to your browser's extension or add-on menu and remove anything you do not recognize or anything labeled as a toolbar, search helper, or optimization tool.
On Windows, open Control Panel, go to Programs and Features, and look for any Yahoo-related software or unfamiliar programs. Click any suspicious entry and select Uninstall. On Mac, open Applications in Finder, look for Yahoo or search-related programs, and drag them to the Trash. Restart your computer after uninstalling, then change your default search engine again. If Yahoo still returns, run a malware scan using Windows Defender (Windows) or Malwarebytes (Mac or Windows).
Removing Yahoo toolbars and search bars from your browser
Yahoo toolbars are browser extensions that add a search bar to your browser window. Even if you change your default search engine, a Yahoo toolbar will still appear and may redirect searches to Yahoo. To remove it, go to your browser's extension menu: the puzzle piece in Chrome, the puzzle piece in Edge, the three horizontal lines then Extensions in Firefox, or Safari's menu then Preferences then Extensions.
Find any extension with "Yahoo" in the name or any toolbar you do not recognize. Click it and select Remove, Delete, or Uninstall depending on your browser. Some toolbars also install as programs on your computer — check your Programs and Features (Windows) or Applications folder (Mac) for anything labeled Yahoo Search, Yahoo Toolbar, or similar, and uninstall it there as well.
Blocking Yahoo on Android and other mobile devices
On Android, open Chrome and tap the three vertical dots in the bottom right. Select Settings, then tap Search engine. Choose Google, Bing, or DuckDuckGo from the list. On Firefox for Android, tap the three horizontal lines at the bottom, select Settings, tap Search, and choose a different engine.
Samsung Internet (the default browser on Samsung phones) has its own search settings. Open the app, tap the three horizontal lines, select Settings, tap Useful features, then Search engine, and choose a different option. Mobile browsers do not share settings with their desktop versions, so you must change the default on each device separately.
Frequently Asked Questions
Will blocking Yahoo affect my Yahoo email or Yahoo account?
No. Changing your search engine only affects which search engine appears in your browser's search bar. Your Yahoo email account, Yahoo Mail login, and any Yahoo services you use will continue to work normally. You can still visit Yahoo.com directly if you need to.
Why does Yahoo keep coming back even after I change my default?
A hijacker extension or program is likely resetting your settings automatically. Check your browser extensions and your computer's installed programs for anything Yahoo-related or unfamiliar, and uninstall it. Restart your computer and browser, then change your default again. If it persists, run a malware scan.
Can I block Yahoo without changing my default search engine?
Yes. If you want to keep your current default but just remove Yahoo from appearing as an option, you can delete it from your browser's search engine list. In most browsers, this is in Settings under Search or Search engine. Find Yahoo in the list, click the three dots or delete icon next to it, and remove it.
What should I do if I accidentally set Yahoo as my default and want to undo it?
Go back to your browser's search engine settings and select a different default. The change takes effect immediately. If you want to return to what you had before, choose the search engine you were using previously. Most browsers remember your previous defaults in the dropdown list.
Do I need to block Yahoo on every device I own?
Yes, if Yahoo is set as default on multiple devices. Browser settings do not sync across devices — your phone's Chrome settings are separate from your computer's Chrome settings. You must change the default search engine on each device individually.
