How Do I Remove Bing as the Default Firefox Search Engine?by Andrew Tennyson
If you are dissatisfied with the quality of Bing's search results or are being redirected to Bing when using another search engine, you can remove Bing as your default search engine. Firefox has a dedicated Manage Search Engines tool designed to help you add and sort search engines. You can also use it to remove the Bing search engine all together.
Removing Bing as the Default Search Engine
Click the “Bing” logo located at the left side of the search bar in Firefox and select “Manage Search Engines.” Select the search engine you want to use instead of Bing as your default and then click the “Move Up” button until the new search engine is at the top of the list. Click “OK” to save your changes.
Deleting Bing and Adding New Search Engines
To remove Bing entirely from the list of available search engines in Firefox, select it from the list of search engines and click the “Remove” button. Click “OK” to save your changes.
If the search engine you want to use is not listed, click the “Get more search engines” link, locate the search engine you want to add and click the associated “Add to Firefox” button.
Removing Bing Malware
If you change your default search engine and Firefox still displays Bing results automatically, you’ve likely been infected with malware. Reset Firefox to fix this problem. Click the three-line “Menu” icon located in the top-right corner of Firefox and then click the “Help” button, identified by a question mark. Select “Troubleshooting Information” and then click “Reset Firefox.”
