Credit Card AutoFill Crashes WebKit Process on Safari 26.0.1

After updating to Safari 26.0.1 on macOS Sonoma 14.8.1, any attempt to autofill a form with a saved credit card will cause the WebKit process to crash. This happens as soon as AutoFill has been authorized via Touch ID or manual password entry. The web page then instantly reloads with the dreaded “This webpage was reloaded because a problem occurred.” banner along the top.

This logging in Console.app seems relevant:

Warning: Exception caught during handling of received message, marking message invalid .
Exception: +[WBSFormDataController getCreditCardControlValuesForFillingInWebView:originatingInFrame:forForm:withMetadataProvider:andCreditCardData:completionHandler:]: unrecognized selector sent to class 0x1f3ba0b70

I had this issue as well....I called apple who wanted me to re-install the OS, which I did. I was skeptical, but it worked. Credit Card Autofill now working :)

I opened a case with Apple support about a week ago. Today they acknowledged that it's a problem due to Webkit and gave me steps to test. (Issue still occurred.) It wouldn't hurt for anyone else that has the problem to also open a case with support....

Another nuisance introduced with Safari 26.0.1 is the painful delay when creating a new tab and typing into the location bar. Safari freezes for 2-3 seconds before it responds to keystrokes. Also, the auto-complete list produces frustratingly inconsistent results for the all-important Top Hit.

There is a Reddit article about this particular bug and it contains a download link to Safari 18.6 for Sonoma. I installed that and everything is back to normal again. Auto-Fill for credit cards works and the location bar is super responsive. What a relief.

It’s so great when they don’t fix the things that matter the most to users. Another 3 months of entering in CC info manually. Or switching to Chrome. Maybe it’s time.

This bug was introduced at the same time as Tahoe was released, so I suspect Safari was updated to handle newer system APIs for credit card access and Sonoma compatibility wasn’t tested as extensively as it should have been. I fear upgrading to Tahoe will be the only solution.

Did you also upgrade the OS, or just Safari? What os version are you on?

In Reddit there’s a similar thread and someone posted an older version of safari installed it and I’m all good. Just as it says above.

For the record, I have the same problem on Sonoma 14.7.5. Problem seems to be Safari 26.0.1 (19622.1.22.118.4)

I have this same problem. A new version of Safari is in beta test so there should be an update at some point. They’re not allowed to tell us what changes were made, but it seems from the posts here that they know about it.

I'm having the same issues with CC auto fill, along with lagging while typing in the address bar. I have Sonoma 14.8.1 and Safari 26.0.1. I would love to downgrade my version of Safari but my web based business software forced my upgrade.
