Web pages crash all the time in Safari on iPhone

If you are experiencing any difficulty with third-party apps or a specific website then please contact the app developer or site publisher/host directly. Here is how

• To contact an App developer --> How to contact an app developer - Apple Support
• To contact a web publisher —> Scroll Down to the bottom of the web page. You will find: Contact Us, Help Center, Support, Terms of use etc.

"It's a misbehaving web page. Safari detects when the page is working improperly and notifies you rather than crash. I use a lot of different web sites and only see this issue very, very rarely."

Use Another Web Browser:

So, what are these Web pages to speak of? Note that not all sites are too fond of Safari. Schools and Banks typically have this issue.

I figured out the issue on my end, it was one of the Safari extensions that caused the issue. After uninstalling them, I’m no longer having the issue.

As for Chrome, when it comes to iOS, all browsers are forced to use the WebKit engine, which is essentially Safari.

Desktop versions of Chrome use the Blink engine.

The reason Chrome would work is because it doesn't load the Safari extensions.

"Web pages crash *all the tine* in Safari: I do this pretty much every day. This isn’t a misbehaving app. It’s something systematic with Safari, and unfortunately, closing apps and restarting don’t work.”

Troubleshooting iOS Safari:

Safari is a builtin app that comes with the iOS. So, check your iPhone for updates.

As a last resort…

Set Up your iPhone Anew:

Set this up anew, as if you were to sell it. Perform as instructed here, including the iCloud logout and backup creation:  What to do Before you Sell, Give Away, or Trade in your iPhone, iPad, or iPod touch - Apple Support. Backup what need be, prior to performing this. All would go to default, and the bugs and glitches would be expected to go away.

"No idea; I personally don't come across them all that often.: Frankly, YouTube seems to trigger the issue more often than most."

Reply with a Screenshot:

Take a screenshot of this message next time you see it, and reply back. Rarely though it may be, seeing the message would most certainly help. If you recall the message's wording, then google it in Google Images, and then reply back with what the image. When an app crashes, something is not responding. Streaming something on your device on a public LAN, you may be using too much of the services, and you're being kicked off.

First of all, if you haven't yet, upgrade to iOS 17.4.

If you still experience issues, you should make an appointment to have your phone examined:

Genius Bar Reservation and Apple Support Options - Apple

as I've never seen that issue on my 15 Pro Max or my 10.5" iPad Pro, let alone any of my Macs.

It could be that this is happening regularly and people don't care, but when it comes to Apple those of us who have been helping users here for many, many years know that just doesn't happen.

As I've also said before, if you feel it is something not operating properly, either make an appointment to have your phone examined:

Genius Bar Reservation and Apple Support Options - Apple

or work with Apple Support directly:

Contact - Official Apple Support

I personally spend hours per day using Safari on my iPhone and have never seen it crash on my iPad or iPhone.

You talk about “so many web applications” crashing when I haven't noticed any.

Regardless, feel free to leave your feedback here:

Feedback - iPhone - Apple

Apple does read and often acts upon feedback left there.

As a developer you can also log issues following the procedure here:

Bug Reporting - Apple Developer

Which is strange, as on iOS all browsers are different appearance/interface packages atop Apple WebKit, which handles all website processing and rendering.

WebKit also handles all HTML processing for iOS such as in Mail.

WebKit | Apple Developer Documentation

• Restart the device. That's it.
• Still not solved --> Force restart iPhone - Apple Support

In my case, the crash was caused by a third-party Safari extension.

An improperly coded web page kept causing errors, which Safari caught rather than crash.

It's telling you it can't make forward progress because the web site is broken.

If an App with Not Respond on an iPhone:

Close All Apps:

An app may not be responding, particularly Safari.. So, close all apps. Hold you finger down as you swipe up. Then, close all of these open apps, by sweeping up quickly for all apps.

A couple of debugging steps:

* It seems Javascript related. Turning off Javascript allows me access to the page(s), they just don't work (because they need Javascript).

* I created a New User on my computer -- NOT an admin -- and I can browse to at least some of the pages as "them" (even if I login to the page as "me"), but still crashes on my main/admin account.

* The pages that crash (one example: after login -- but there are dozens, this is NOT a wave apps problem!), they crash Safari, Chrome, Firefox and DuckDuckGo browsers.

...So maybe the bug is in WebKit?

I don't know enough to offer a strong opinion about where the problem is, I'm just reporting my experience.

In my case, re: my crashes on iPhone browser (both Safari and Chrome), (and yes, it still happens), it may have something to do that I cannot update to IOS 17, because my phone is no longer supported. I’m on IPhone 8.

I just saw I can update to a new IOS 16, maybe that will help.

It is definitely not on every page, only those with lots of ads going on, pages that are heavy to process, and are messy. It’s a little better with Chrome.

Need to figure out getting a new phone, I guess.
