What a default browser does and why it matters
Your default browser is the program that opens automatically when you click a link in an email, text message, document, or anywhere else outside a web browser. Setting one saves you from having to choose which browser to use every single time. Most people have multiple browsers installed — Chrome, Firefox, Safari, Edge — but only one can be the default.
The default browser also handles web addresses you type into your system search bar or voice assistant. If you have never set a default, your computer or phone assigned one when you first set it up. You can change it anytime, and the process takes less than a minute on any device.
Choosing a default is separate from deciding which browser you prefer for everyday browsing. You might use Chrome most of the time but set Firefox as your default because it handles a specific task better, or because you want to keep work and personal browsing separate.
Key Takeaways
- Your default browser opens automatically when you click links outside of a browser, so pick one you trust and use regularly.
- On Windows, go to Settings > Apps > Default Apps and select your browser; on Mac, open System Settings > General > Default Web Browser.
- On iPhone, go to Settings > [Browser Name] and toggle it as default; on Android, go to Settings > Apps > Default Apps > Browser App.
- You can change your default browser as often as you want — there is no penalty for switching, and your bookmarks and passwords stay where they are.
- Your default browser choice does not affect which browser you use for everyday work; you can still open a different one whenever you want.
How to set a default browser on Windows
Open the Windows Settings app by pressing the Windows key and typing "Settings," then pressing Enter. Click Apps in the left sidebar, then scroll down and click Default Apps.
Scroll down the list until you see Web Browser. Click on it, and a window will show all the browsers installed on your computer. Click the one you want to use as your default. Windows will confirm the change when ready — you do not need to restart your computer.
If the browser you want does not appear in the list, it may not be installed yet. read it from the browser's official website, then return to this same Settings screen and select it.
How to set a default browser on Mac
Click the Apple menu in the top-left corner and select System Settings. Click General in the left sidebar, then scroll down and click Default Web Browser.
A dropdown menu will show every browser installed on your Mac. Click the one you want, and the change takes effect when ready. You can return to this same screen anytime to switch to a different default.
How to set a default browser on iPhone
Open the Settings app and scroll down until you find the name of the browser you want to set as default — for example, Chrome, Firefox, or Edge. Tap it to open that browser's settings.
Look for an option called Default Browser App or Set as Default Browser, and toggle it on. The exact wording varies by browser, but the setting is always in that browser's own settings section, not in the main iOS Settings.
If you do not see the option, the browser may not support being a default on your version of iOS. Update the browser through the App Store and check again.
How to set a default browser on Android
Open the Settings app and go to Apps. Tap Default Apps (the exact name varies by phone brand — it may say Default Applications or App Defaults).
Look for Browser App or Web Browser in the list. Tap it and select the browser you want from the list that appears. The change is when ready.
If you have already set a default and want to change it, return to this same screen and select a different browser. Android will ask you to confirm before switching.
Choosing between browsers for your default
The best default browser is one you already use and trust. If you spend most of your time in Chrome, set Chrome as your default — that way, links open in the browser where your bookmarks and passwords already are. If you prefer Firefox for privacy reasons, set Firefox as your default instead.
Some people set different defaults for different purposes. You might use Chrome as your default for personal browsing but keep Edge as your default on a work computer. You can change your default as often as you want; there is no cost or penalty, and your bookmarks, passwords, and browsing history stay exactly where they are.
If you are unsure which browser to choose, start with whichever one you installed most recently or use most often. You can always change it later if you find a browser that works better for you.
What happens if you do not set a default browser
If you have never set a default, your device assigned one automatically when you first set it up. On Windows, this is usually Edge. On Mac, it is Safari. On iPhone and Android, the system default varies by device.
You can find out which browser is currently your default by going through the steps above for your device — the current default will be highlighted or checked. If you are happy with it, you do not need to change anything. If you want a different one, follow the steps in the section for your device type.
Frequently Asked Questions
Will changing my default browser delete my bookmarks or passwords?
No. Your bookmarks, passwords, and browsing history stay in the browser where you created them. If you switch your default from Chrome to Firefox, your Chrome bookmarks remain in Chrome. You can still open Chrome anytime and access everything there.
Can I set a different default browser on my phone and computer?
Yes. Your phone and computer are separate devices with separate settings. You can set Chrome as your default on your computer and Firefox on your phone, or any other combination. Each device remembers its own default independently.
What if a link opens in the wrong browser?
The link opened in your current default browser. Go back to the Settings steps for your device and confirm which browser is set as default. If it is not the one you want, select a different one. If you just changed it and a link still opened in the old browser, you may need to close and reopen the app that sent the link.
Do I need to uninstall other browsers if I set one as default?
No. You can keep as many browsers installed as you want. Setting one as default only means that one will open automatically when you click links. You can still open any other browser manually whenever you choose.
Can websites tell which browser is my default?
No. Websites can see which browser you are currently using to view them, but they cannot see which browser you have set as your system default. Your default browser choice is a setting on your device only.
