It&#8217;s built into Firefox&#8217;s own search list and it&#8217;s the default in Microsoft Edge, so seeing Bing isn&#8217;t proof of malware.<\/p>\n<p>The trouble starts when Bing replaces your pick. Firefox asks before an add-on makes its search engine your default, so one quick yes during an install can do it.<\/p>\n<p>On a Mac, a configuration profile can also set Firefox&#8217;s default search engine. Mozilla built that for IT departments, but a profile you never installed can use it too.<\/p>\n<p>One easy mix-up: Firefox&#8217;s search menu lets you send a single search to another engine. Picking Bing there by mistake looks like a redirect but leaves your default alone.<\/p>\n<h3>Quick fix: get Bing out of Firefox in four steps<\/h3>\n<p>Do these in order and run a test search after each one. Stop as soon as Bing is gone.<\/p>\n<ol>\n<li>Open Firefox &gt; Settings &gt; Search and pick Google or another engine under Default search engine.<\/li>\n<li>On the same page, under Additional search engines, switch off the toggle next to Bing so Firefox stops offering it.<\/li>\n<li>Type about:addons, click Extensions and remove anything you don&#8217;t recognize, especially search or new-tab add-ons.<\/li>\n<li>Quit Firefox with Command+Q, reopen it and search again. If Settings says Firefox is managed by your organization, open about:policies next.<\/li>\n<\/ol>\n<h3>What to do if Bing comes back<\/h3>\n<p>If Bing returns after a restart or login, the cause sits outside Firefox&#8217;s normal settings. Check about:policies, Device Management in System Settings, and your login items.<\/p>\n<p>You may read that Microsoft 365 switched browsers to Bing. That add-on targeted Google Chrome, not Firefox, and Microsoft retired it on March 31, 2025.<\/p>\n<p>Follow the five steps below in order. Save the advanced checks for a locked setting or a Bing redirect that keeps returning.<\/p>\n<p><!-- mt-nov-module supported-symptoms 48b335dc1a4c5be5472e72158d14e9445b5fdd0547cce43f6a97f719434e0611 --><\/p>\n<p>These fixes handle a hijacked search engine, unwanted extensions and Mac adware.

If an employer or school manages this Mac, check with IT before touching profiles or startup settings.<\/p>\n<p><!-- \/mt-beginner-module --><\/p>\n<h3>Look for a policy that sets Firefox to Bing<\/h3>\n<p>Open about:policies and note the active rules. A search engine rule, an add-on rule or a locked setting can explain why Firefox ignores your choice.<\/p>\n<p>Mozilla says the &#8220;managed by your organization&#8221; notice can come from an IT administrator, security software or a local policy. It doesn&#8217;t automatically mean infection.<\/p>\n<p>On a Mac run by your work or school, ask the IT team about these rules before changing anything.<\/p>\n<p>Firefox can also load rules from a policies.json file. Mozilla lists its Mac location as Firefox.app\/Contents\/Resources\/distribution.<\/p>\n<p>Only open that file if about:policies points there. Keep the original, and don&#8217;t edit the app or delete every policy as a routine fix.<\/p>\n<p>A user.js file inside your profile can put Bing back at each launch. Compare what it sets with the setting that keeps reverting.<\/p>\n<p>Find the right profile folder in about:support. Quit Firefox before any change an expert recommends, and keep a backup copy.<\/p>\n<p>Don&#8217;t delete prefs.js, user.js and other profile files together to see what happens. You lose the comparison and unrelated settings along with them.<\/p>\n<h3>Check Mac profiles and apps that restore Bing<\/h3>\n<p>Open System Settings, General, Device Management if it&#8217;s there. Look at who issued each profile and what it configures, not just its name.<\/p>\n<p>Mozilla supports configuration profiles for Firefox settings, including the default search engine. A profile you never installed that mentions Firefox deserves a close look.<\/p>\n<p>A Firefox profile and a macOS configuration profile are different things. Removing one never removes the other.<\/p>\n<p>Removing a configuration profile can also take away accounts, VPN access and certificates. Note those settings and remove only a profile you&#8217;ve confirmed is unwanted.<\/p>\n<p>If Bing comes back after you log in, check Applications and General, Login Items &amp; Extensions. Look for an app clearly linked to the add-on or setting you found.<\/p>\n<p>Uninstall that app the way its developer documents. A recent or unfamiliar app isn&#8217;t automatically the culprit.<\/p>\n<p>LaunchAgents and LaunchDaemons can start helpers at login, but they aren&#8217;t folders to empty. Have each item&#8217;s program path checked before changing it.<\/p>\n<p>Keep legitimate security, backup and device helpers. When in doubt, gather details for support instead of disabling everything that runs in the background.<\/p>\n<p><!-- mt-beginner-module advanced-firefox fe0a8a44becea8383a0146a9e32774f1e56a7d950ad10473a9d069d21c06ea25 --><br \/>\n<!-- mt-local-illustrated-guide source=firefox-platform-guide; source\/file hashes in tutorial-library.json --><\/p>\n<h4>Compare with Troubleshoot Mode first<\/h4>\n<p>From the Help menu, called Help and Report in some releases, pick Troubleshoot Mode. Firefox asks to restart, so save anything open first.<\/p>\n<p>Try the search that goes to Bing. This temporary mode disables add-ons and some custom settings, but it doesn&#8217;t uninstall Mac software or lift enterprise policies.<\/p>\n<p>No Bing in Troubleshoot Mode? An add-on is the likely cause, so test them one by one. Still Bing? Look at policies, the default engine setting and Mac software.<\/p>\n<h4>Try a clean test profile<\/h4>\n<p>Create a new, clearly labeled profile from about:profiles or Firefox&#8217;s profile menu. Leave Sync and imported add-ons switched off for now.<\/p>\n<p>Search from the new profile and open about:policies. Policies set for the whole Mac apply to every profile.<\/p>\n<p>Clean profile works? The old profile holds the cause. Both fail? Something outside Firefox&#8217;s profiles is pushing Bing.<\/p>\n<p>Don&#8217;t pick Delete Files on your main profile for this comparison. Your data should stay recoverable.<\/p>\n<p>about:support shows the active profile folder if a helper needs it. Quit Firefox fully before copying or editing anything inside.<\/p>\n<p>Once fixed, bring back trusted add-ons and Sync data gradually, and note any step that brings Bing back.<\/p>\n<p><!-- \/mt-beginner-module --><\/p>\n<h2>Pin Down Exactly When Bing Appears<\/h2>\n<p>Note the first action that lands on Bing. Is it Command+L, an add-on&#8217;s page, a saved bookmark, or a homepage that opens by itself?<\/p>\n<p>Search for something harmless and watch the address bar. If a strange site flashes before bing.com, write down its name but not your search terms.<\/p>\n<p>Open your chosen search engine&#8217;s website directly and search there. If that works, the problem is in Firefox&#8217;s address bar or default setting.<\/p>\n<p>Back up bookmarks and account details before bigger repairs. Keep one working profile untouched so you have something to compare against.<\/p>\n<p>Use Firefox&#8217;s built-in pages for this. Installing an unknown add-on to trace redirects adds one more suspect and can expose your browsing.<\/p>\n<h2>If Safari or Chrome Also Go to Bing<\/h2>\n<p>Test Safari or Chrome separately. Two browsers set to Bing on purpose don&#8217;t prove a shared hijacker.<\/p>\n<p>If several browsers pass through the same strange site before Bing, look for a shared app or network setting. Write down that site&#8217;s name.<\/p>\n<p>Proxy, DNS or VPN settings may matter then. Record the current values before changing anything.<\/p>\n<p>Don&#8217;t reset every network setting on your Mac for a problem limited to one Firefox add-on. You&#8217;d lose connection settings without removing the add-on.<\/p>\n<p>If a page or caller asks for remote access to fix your search, say no. Use your IT team or a trusted support channel.<\/p>\n<\/details>\n<h2>What to Do If Firefox Still Opens Bing<\/h2>\n<ol>\n<li>\n<p>Write down the exact search that fails, the Firefox profile, any site that flashes before Bing, and what brings Bing back.<\/p>\n<\/li>\n<li>\n<p>Keep your policies, add-on list, scan reports and file backups. Share short, redacted excerpts rather than a full browser profile.<\/p>\n<\/li>\n<li>\n<p>Get Mac help in the <a href=\"https:\/\/malwaretips.com\/forums\/mac-malware-removal-help-support.183\/\">MalwareTips removal-help forum<\/a>, or ask IT if your employer or school manages the Mac.<\/p>\n<\/li>\n<\/ol>\n<p>If you typed a password into a page that appeared during the redirect, change it on the real site.

In Firefox on a Mac, the likely causes are an add-on, a policy from a configuration profile, or an app that runs at login.<\/p>\n<p>Changing the setting alone won&#8217;t hold until that source is gone. Steps 1 and 2 above handle the add-on case.<\/p>\n<h3>Is Bing a virus on my Mac?<\/h3>\n<p>No. Bing is Microsoft&#8217;s search engine, and Firefox includes it in its built-in list. The thing to remove is whatever forces it on you.<\/p>\n<p>If a strange site flashes before Bing loads, treat that as possible adware and run the scan in Step 3.<\/p>\n<h3>Why does Google redirect to Bing in Firefox?<\/h3>\n<p>Your default may have been switched, or an add-on may be rewriting searches. Choosing Bing in Firefox&#8217;s search menu also sends that one search there.<\/p>\n<p>Set Google again in Settings, Search, then test in Troubleshoot Mode with add-ons off. If Bing disappears there, an add-on is responsible.<\/p>\n<h3>How do I get rid of Microsoft Bing on my Mac completely?<\/h3>\n<p>In Firefox, choose another default and switch off Bing&#8217;s toggle under Additional search engines. That hides it from Firefox&#8217;s search options.<\/p>\n<p>Bing stays available as a website. Microsoft Edge also keeps Bing as its default until you change Edge&#8217;s own search settings.<\/p>\n<h3>Did Microsoft Edge or Microsoft 365 change Firefox to Bing?<\/h3>\n<p>Not by design. Edge&#8217;s Bing default only applies inside Edge. The Microsoft 365 add-on that set Bing was built for Google Chrome, and Microsoft retired it in March 2025.<\/p>\n<p>If Firefox switched anyway, look for an add-on or configuration profile installed around the same time.<\/p>\n<h3>What if the Mac scan finds nothing?<\/h3>\n<p>That can be normal. A scanner can remove an adware app, but changed browser settings and profiles may still need fixing by hand.<\/p>\n<p>Keep checking the default search engine, your add-ons and about:policies. A clean scan can&#8217;t prove those are set the way you want.<\/p>\n<h2>The Bottom Line<\/h2>\n<p>When Firefox redirects to Bing on Mac, pick your search engine in Settings, remove the add-on behind it, and switch off Bing&#8217;s toggle if you never use it.<\/p>\n<p>If Bing returns after a restart, check about:policies, Device Management and your login items. Remove only what you can link to Bing, and leave work profiles alone.<\/p>\n<p>Still seeing Bing?
