How to change your default search engine

The short answer

In every major browser the default search engine is a dropdown inside Settings, not in any right-click or toolbar menu: Chrome and Edge put it under a Search engine heading, Safari puts it in a Search tab, and Firefox puts it in a Search panel. Change the dropdown and every query you type into the address bar from that moment on goes to the engine you picked.

As of August 2026, on current desktop versions, the four fastest routes are:

• Chrome — paste chrome://settings/search into the address bar, then set Search engine used in the address bar.
• Edge — paste edge://settings/search, then set Search engine used in the address bar.
• Firefox — open the ☰ menu, choose Settings, then Search, then Default Search Engine.
• Safari on macOS — Safari menu, Settings…, Search tab, Search engine.
• Safari on iPhone or iPad — the Settings app, Apps, Safari, Search Engine.

That is the whole mechanical task, and it takes about fifteen seconds. Everything below is the part people actually get stuck on: why the setting is hidden in the first place, why the change sometimes undoes itself, why the box on your new-tab page can keep using a different engine than your address bar, and how to tell a setting you changed from a setting something else changed for you.

Why a one-line setting is buried five clicks deep

The default search engine is the most commercially valuable preference on a personal computer, and it is buried because it is valuable. Search engines pay browser and device makers enormous sums for that dropdown to arrive pre-set, and the money only makes sense if most people never open the menu. Every extra click between a user and the setting is worth money to whoever is currently selected in it.

This is not a suspicion; it is a finding of fact. In United States v. Google LLC, Judge Amit Mehta ruled on 5 August 2024 that Google "is a monopolist, and it has acted as one to maintain its monopoly," identifying its exclusive default-placement contracts — notably with Apple — as the unlawful conduct. The same opinion put Google's share of general search at roughly 90%, and around 95% on mobile. Defaults, in other words, were found to be the mechanism by which the market stayed the shape it was.

The remedies decision of 2 September 2025 is worth knowing about because it is routinely misdescribed. Structural relief was rejected: no Chrome divestiture was ordered. What was banned was exclusivity — Google may no longer sign or maintain exclusive distribution agreements for Google Search, Chrome, Assistant or Gemini — while paid, non-exclusive default placement on terms of a year or less remains permitted. Google must also syndicate results and share click-and-query data with qualified competitors under the judgment, which runs six years. Both sides appealed; as of August 2026 the D.C. Circuit had not ruled.

The practical upshot: the payments that put an engine in your dropdown before you ever opened it are still legal, and nothing in the ruling changes the setting for you. It remains a thing you do by hand.

The address bar and the new-tab box are different settings

This is the single most common reason people believe their change "did not work." In several browsers the search engine used by the address bar and the search box drawn on the new-tab page are governed separately, so a query typed into one goes somewhere different from a query typed into the other.

Microsoft Edge is the clearest case. Changing Search engine used in the address bar does not, by itself, change what the search box on the Edge new-tab page does — that box has historically routed to Bing regardless. The relevant control sits on the same settings page under a heading about what search on new tabs uses, where the choice is between the new-tab search box and the address bar; selecting the address-bar option is what makes the new-tab page respect your default engine.

Chrome couples them, but changes the page. With Google set as the default, the new-tab page is Google's own: logo, search box, shortcuts. Select any other engine and Chrome swaps in a generic new-tab page whose search box hands queries to your chosen engine. Some users read that visual change as breakage; it is the expected result.

Firefox has three related surfaces rather than two — the address bar, the optional separate search bar in the toolbar (off by default; you add it in the same Search settings panel), and the search box on Firefox Home. The Default Search Engine setting governs all three, and a separate checkbox controls whether private windows use that same engine or a different one.

Safari keeps one engine setting for the unified smart search field, plus a separate control for which engine Private Browsing uses. Safari's Start Page has no independent search box to disagree with it.

What the EU choice screens changed, and what they did not

If you are in the European Union, you may have been shown a screen listing search engines and asked to pick one, rather than being given a pre-set default. That is a consequence of the Digital Markets Act, under which the European Commission designates very large platforms as "gatekeepers" and imposes obligations on them, including choice screens for defaults on the operating systems and browsers they control.

Two details are worth getting right, because they are widely mangled. First, designation is per service, not per company: per the Commission's own gatekeeper register, Alphabet's Google Search is a designated core platform service, while Microsoft's designated services are LinkedIn and the Windows PC operating system — Bing is not designated. Second, choice screens predate the DMA. Google was already running a search-engine choice screen on Android in Europe as a remedy in the earlier Commission antitrust case, originally allocated by a paid auction and reworked into a free format in 2021; Presearch, among others, gained EU Android distribution through it. In Russia, a 2017 settlement with the antitrust authority produced a comparable Android choice screen after a complaint by Yandex.

What the choice screens changed is the first moment of the decision — an unavoidable menu instead of a silent pre-selection. What they did not change is anything after it. A choice screen sets the default once; it does not stop the setting being changed later by software you install, it does not exist outside the EU for most surfaces, and it does not reach the search boxes inside individual apps. Outside Europe, the pre-set default remains the outcome of a commercial agreement, and the dropdown is the only remedy available to an individual.

What actually happens to your searches after you switch

The change takes effect on the next query and nothing retroactive happens. Open tabs stay open and keep whatever results they are already showing; history, bookmarks and saved passwords are untouched; a results page you already loaded from the old engine does not reload. Only the routing of new queries typed into the address bar changes.

Three things people expect to happen do not. Your old engine does not forget you — searches already logged stay logged, and if you remain signed in to a Google or Microsoft account, visiting that engine's own site directly still associates the query with the account. Your browser vendor does not stop being your browser vendor: using DuckDuckGo inside Chrome still leaves Chrome handling the connection, the sync, and the crash telemetry. And search suggestions in the address bar are a separate toggle in most browsers, so typed characters may still be sent somewhere for autocomplete until you turn that off.

The larger point is that switching the dropdown does not automatically mean switching indexes. Several popular alternatives do not run a web crawler of their own: Startpage deliberately re-serves Google results with the identifying data stripped, and says so; DuckDuckGo and Ecosia blend their own layers over a partner's results rather than ranking an independent index. Brave Search and Mojeek do crawl and rank their own. If your reason for changing the setting is to see genuinely different results rather than the same results delivered privately, the distinction between an engine with its own index and one reselling somebody else's is the thing to check before you pick.

Why the setting sometimes reverts

A default that comes back after a restart is almost never a browser bug. There are five ordinary explanations, in rough order of how often they turn out to be the cause.

1. An extension owns the setting. Browser extensions can legitimately declare a search provider, and once one does, the dropdown is locked to it. Chrome and Edge say so on the settings page itself with wording about the setting being controlled by an extension; the fix is to remove the extension, not to fight the dropdown.
2. Sync overwrote it. Signed-in profiles synchronise preferences across devices. Change the engine on one machine while another still has the old value and the old value can propagate back.
3. A managed policy is in force. Work and school devices — and, less benignly, machines carrying leftover policy keys from bundled software — can have the default set by administrative policy. The tell is a note that the browser is managed by your organisation, and a greyed-out control.
4. You changed a different setting than you thought. Setting the address-bar engine in Edge while judging the result by the new-tab search box is the classic version of this.
5. An update or reinstall reset the profile. Rare, but a repaired or recreated profile takes the shipped default.

If none of those fit, and particularly if the setting reverts to an engine you have never heard of, the cause is more likely to be a hijacker than a preference.

Telling a preference from a hijack

A genuine preference change has three properties: you initiated it, the engine is one you can name, and it persists until you change it back. A hijack fails at least one of those. The reliable signals are behavioural rather than cosmetic.

• The engine changed without you opening Settings, typically after installing free software, a video downloader, a PDF converter or a browser theme.
• The dropdown is greyed out, or shows an unfamiliar name, or reports that it is managed by an organisation on a personal machine.
• A search visibly bounces through one or more intermediate domains before landing on a mainstream results page — the redirect chain is the monetisation, since the operator collects a partner fee on traffic passed to a real engine.
• The homepage and the new-tab page changed at the same time as the search engine. Legitimate engine changes do not touch your homepage.

Reversal is a matter of finding whichever mechanism keeps re-applying the setting — an extension, a policy key, a modified shortcut, a configuration profile — and removing that, rather than resetting the dropdown repeatedly.

The harder question is what to change it to

Once the mechanics are done the interesting decision remains, and it is not the one most switching guides pose. The useful question is not "which engine is best" but "whose index am I about to start reading, and how is it paid for?" Those two answers determine what you will see far more than any interface preference.

Very few organisations crawl and rank the open web independently — Google, Microsoft Bing, Yandex, Baidu, Brave Search, Mojeek and a short list of others. Everything else, including several engines marketed as alternatives, is a front end over one of those indexes with different privacy handling, a different interface, or a different revenue model attached. That is not a criticism: Startpage's entire product is Google results without Google's logging, and it is honest about it. But it does mean that changing your default from Google to a Google reseller changes who holds your query, not which pages you are shown.

The other axis is funding. An engine funded by advertising has an incentive to fill the top of the page; an engine funded by subscription has an incentive to fill it with results; an engine funded by neither is usually running on borrowed time. Choosing between them is a genuine trade-off with no universally correct answer, and it deserves more thought than the dropdown itself,.
