How to Set Opera GX as Your Default Browser on Any Device

Opera GX has carved out a loyal following among gamers and power users who want more control over their browsing experience — RAM limiters, CPU caps, built-in Discord integration, and a dark aesthetic that most browsers don't offer. If you've decided Opera GX is where you want to spend most of your time online, making it your default browser is the logical next step. Here's how to do it across different operating systems, plus what you should know before you make the switch.

What "Default Browser" Actually Means

Setting a browser as your default tells your operating system to open that browser automatically whenever you click a link — whether that's in an email, a document, a chat app, or another piece of software. Without a default set, your OS either prompts you to choose or falls back on whatever browser was installed at the factory (usually Edge on Windows or Safari on macOS).

Changing your default doesn't uninstall other browsers or prevent you from using them. It simply redirects link-click behavior system-wide.

How to Set Opera GX as Default on Windows 10 and Windows 11

Windows handles default browser settings through the Settings app, not through the browser itself — though Opera GX does offer a shortcut to get there.

Method 1: Through Opera GX

1. Open Opera GX and click the Opera logo (top-left menu button).
2. Go to Settings → Browser → scroll down to Default browser.
3. Click Make Opera GX your default browser.
4. Windows will open the Default Apps settings panel automatically.

Method 2: Through Windows Settings

1. Press Windows + I to open Settings.
2. Go to Apps → Default apps.
3. Search for Opera GX in the app list.
4. Click on it and set it as the default for HTTP, HTTPS, and optionally .htm and .html file types.

🖥️ Windows 11 note: Microsoft made default browser switching more granular in Windows 11 — you need to set defaults per protocol and file type individually, not as a single toggle. This adds a few extra clicks but works the same way.

How to Set Opera GX as Default on macOS

Opera GX for macOS follows a different path since Apple manages default apps through System Settings.

1. Open Opera GX on your Mac.
2. Click the Opera GX menu in the top menu bar → Preferences.
3. Under Browser, find Default browser and click Make Opera GX your default browser.

Alternatively:

1. Open System Settings (macOS Ventura and later) or System Preferences (earlier versions).
2. Go to Desktop & Dock → scroll to Default web browser.
3. Select Opera GX from the dropdown.

If Opera GX doesn't appear in the dropdown, make sure it's fully installed and has been opened at least once.

How to Set Opera GX as Default on Android

Opera GX is available on Android, and setting it as the default browser requires adjusting your device's app link settings.

1. Open your Android Settings.
2. Go to Apps → find and tap Opera GX.
3. Tap Set as default or Open by default.
4. Enable Open supported links and confirm Opera GX as the handler for web links.

Note: The exact menu path varies by Android version and device manufacturer (Samsung, Google Pixel, OnePlus, etc.). On some devices, you'll find this under Default apps in the Apps settings menu rather than inside the individual app's settings.

Variables That Affect How This Works

Not every setup behaves identically. A few factors determine whether the switch goes smoothly:

When Other Apps Override Your Default

One thing users frequently run into: some apps ignore your system default entirely. Microsoft Office apps on Windows may open links in Edge regardless of your default setting. iOS doesn't support Opera GX as a system-wide default in the traditional sense, since Apple restricts this to Safari. Some corporate productivity tools have their own embedded browsers.

This means your actual browsing experience after setting a default depends on which apps you're clicking links from, not just which browser you've designated as default.

The Spectrum of Outcomes

For most casual users on a personal Windows or macOS machine, setting Opera GX as default is a one-time, five-minute task with no complications. For users on Android with a heavily customized manufacturer skin, it may take a few extra steps to locate the right settings menu. For users on managed corporate devices or within certain ecosystems (heavily Microsoft-integrated environments, for example), system policies or app-level behaviors may partially limit how completely Opera GX takes over as the default.

Whether the switch fully delivers what you're expecting depends on your specific device, OS version, and which applications you use most often to open links — details only your own setup can answer. 🎮
