[iOS 26 DB 1] Safari not syncing bookmarks and lost all open tabs Bug; When I updated I lost all my open tabs from Safari and my bookmarks disappeared and are not syncing anymore. Reset iCloud sync as well — from Reddit.
With the release of iOS 26 Beta, Many users report that open tabs vanish after rebooting or relaunching Safari, and that bookmarks fail to sync across devices running different iOS versions.
These bugs are affecting daily workflows and causing concern about potential data loss. This guide explores what’s causing these Safari issues and offers reliable solutions, including the fix solution and how to restore Safari tabs on iPhone or recover lost bookmarks without needing a backup.
One of the most reported issues with iOS 26 Beta is that open Safari tabs disappear randomly. After updating to the beta version, some users find that previously open tabs are no longer present — even after enabling "Show All Windows" in Safari.
Why does this happen? Beta versions are not fully stable. Memory management bugs, app crashes, and sync errors can lead to tab data corruption. Once this happens, Safari does not provide a native option to restore lost tabs.
Another common problem is bookmarks not syncing properly between iOS 26 devices and older iPhones, iPads, or Macs. Apple is aware of this issue, but no official fix is available yet.
If you see bookmarks missing after syncing, or newly added bookmarks not appearing on all devices, you are likely encountering this beta sync bug. Unfortunately, unsynced or deleted bookmarks may not reappear even if you revert to an older iOS version.
Before moving to more advanced solutions, it’s always worth trying a few basic troubleshooting steps. These can sometimes resolve temporary sync issues caused by iOS 26 Beta bugs — especially if the problem appeared shortly after an update.
Restarting iCloud Safari sync forces your device to re-download bookmark data and resync open tabs across all connected devices. This is often an effective first step.
Go to Settings > [your name] > iCloud.
Tap ‘See All’ and find Safari.
Toggle Safari off, wait 30 seconds, then turn it back on. Then open Safari and check whether your missing tabs or bookmarks have reappeared
If restarting sync didn’t work, signing out of iCloud and signing back in can trigger a more complete data resync — which sometimes restores lost Safari data.
Go to Settings > [your name] and scroll down.
Tap ‘Sign Out’. You’ll be asked whether to keep a copy of iCloud data — select ‘Yes’.
Restart your iPhone, then sign back into your iCloud account. Wait several minutes for iCloud to re-sync Safari data. Check Safari again to see if the missing bookmarks or tabs are restored.
If basic syncing solutions didn’t work, you can use UltData iOS Data Recovery to recover missing Safari data even without iCloud or iTunes backup. UltData scans your iPhone’s internal database to retrieve deleted Safari tabs and bookmarks.
This is particularly useful if iOS 26 Beta bugs caused data loss that can’t be reversed through sync methods.
Download and install Tenorshare UltData from the official website. Connect your iPhone and choose “iPhone/iPad Data Recovery”.
.Select “Safari Bookmarks” and “Safari Hisrtory”and begin the scan.
Preview the recoverable items and restore them with one click.
That’s it! In a few minutes, you’ll be able to restore lost Safari bookmarks and reopen important tabs manually using recovered browsing history.
Now that you’ve recovered your data (or know how to), it’s time to take steps to protect it in the future. Here are some expert tips:
Back up Safari data regularly: Use iTunes or iCloud backups to ensure you always have a recent copy of Safari data.
Avoid running beta versions on your primary device unless absolutely necessary. Beta software is prone to bugs and unexpected behavior — always test on a secondary device if possible.
Export your Safari bookmarks periodically as an HTML file. This ensures you have an external copy you can import if anything goes wrong.
Safari issues in iOS 26 Beta are frustrating but not irreversible. Whether your open tabs disappeared or bookmarks stopped syncing, this guide helps you troubleshoot the problem step-by-step. And if nothing else works, Tenorshare UltData offers a professional way to recover Safari data — even without backups.
Yes. If the tabs were recently closed, you can often reopen them by tapping the Tab Overview button and selecting Recently Closed Tabs. However, if tabs were lost due to a system crash or update bug, you may need to check your Safari History to manually revisit important pages.
If you’ve previously backed up your iPhone to iCloud or iTunes, restoring that backup can restore Safari history as well. Without a backup, recovering history can be more difficult — but some data recovery tools can help extract it from your device.
If you didn’t back up via iCloud, you still have options. In some cases, bookmarks may be recoverable through Safari History or a local device scan. It’s best to act quickly before deleted data is permanently overwritten.
