Safari browser is upgraded regularly, it receives one major version upgrade a year and minor patch fixes and upgrade intermittently. If you haven’t upgraded your browser for long time (missing a few major upgrades), then you might encounter the error saying “This version of Safari is no longer supported”. In such case, you need to update your Safari on iPhone or iPad to make it compatible with latest web technology and tweak JavaScript settings.

Usually, when trying to access a specific website using Safari browser, it will throw this error at you and won’t load the website. In this article, I have explained why you come across this warning on the Safari browser, along with valuable tips on fixing this issue.
The reasons for your encounter might be anything. You forgot to update the Safari browser app to a newer version. So, the older build of Apple’s native browsing app encounters bugs and errors. When you launch a website on Safari, that website(or some of its features) is functionally incompatible with the older version of Safari on your iPhone.
If somehow the JavaScript has been disabled on the Safari browser, then specific components of most websites will not load. That may lead to the outdated Safari build problem.
Check out these troubleshooting tips and implement them to fix the unsupported browser error in Safari on iPhone or iPad.

Install the Latest iOS Version
Currently (as of Sept 2023), Apple iPhones are running the latest iOS 17 on their system. If your iPhone is still using a previous iOS, it will have many complications in using the Safari app and accessing dynamic websites on it.

- Make sure your iPhone is connected to WiFi.

button.
Follow the instructions to finish the update and reboot the iPhone. Once the iPhone restarts, launch Safari, browse your choice of website, and check if you are seeing the unsupported version error.
Update Safari App
The Safari browser is integrated as part of system updates in iOS or iPadOS. However, if you have an older iPhone or iPad device, the Safari app might be available as a standalone app in the App Store.
Hence, you might be required to update the Safari from the App Store. To update Safari on your device:
- Launch the App Store app.
- At the top-right corner, tap the Apple ID avatar.
- On the next page, check if Safari has an Update Pending.
- If a new build of Safari is available, tap on the command button.
- After updating Safari, relaunch it from the home screen or App Library.
Force Close Safari Browser
If you have installed the latest update for Safari and it is still throwing the “This version of Safari is no longer supported” at you, force close the browsing app. Then, relaunch it. iOS enthusiasts have often suggested this trick to fix random glitches with the iPhone apps. To force close the Safari app:
- If you use an iPhone with Touch ID, press the home button twice, OR if you have an iPhone with Face ID, then swipe up from the bottom of the display to launch the App switcher.
- Scroll horizontally to the Safari app card, swipe it up, and close the app.
- Please wait a few seconds and tap the Safari app icon to relaunch it.
Most likely, the problem should be sorted now, and you can browse your choice of websites smoothly.
