Safari crashing due to excessive tabs on iPad Air

Hi, my son’s iPad Air safari not responding/keeps crashing. I believe there’s too many tabs open, when clicking clear history and data button in settings it’s saying there’s just over 36,000 tabs open (don’t ask!), so cick the red button and nothing happens for ages and then window just closes and returns to Home Screen. Have trawled the internet and tried every thing that’s suggested. If it helps safari/advanced/website data says 0 bytes. Any ideas would be appreciated. Ta

Hi, list of things tried in no particular order and probably not conclusive as my poor old brain doesn’t retain stuff as well as used to!
turned off then on, force quit safari, iOS up to date, restart app, airplane mode on off, blocked cookies, Java script off, web kit feature flags all off,screen time off,I cloud sync off, safari extensions off,content and privacy off (the above were on ). A different browser works ok. And a pic of displayed safari page. Thanks


Feature flags should be set to default, not off. That set to off is likely to cause problems. Scroll to the bottom, and select “default”


Settings > Apps > Safari > Advanced > Feature Flags > (scroll down) [default]


Settings > Apps > Safari > Close Tabs > [One Day, or as appropriate]


Settings > Apps > Safari > Extensions > [all off]


Settings > Apps > Safari > Advanced > JavaScript > [on] (JavaScript is now a near-ubiquitous web dependency)


Settings > Apps > Safari > Advanced > Website Data > [remove all]


Settings > Apps > Safari > Automatically Save Reading List Offline > [off]


Settings > Apple Account > iCloud > [tap on Saved to iCloud / see all apps] > Safari > [off].


Now force-restart the iPad. Re-enable iCloud tabs for Safari.

Hi, thanks for reply, everything was turned off after following tips from internet! Have done as you suggested but still when I go settings, apps, safari, clear history (showing 36000 open tabs)I then tap red button and it just hangs for a good 30 seconds then returns to Home Screen. Am thinking needs a full reset (have backed everything up to iCloud) unless there’s any other ideas. Thanks again.

Did you also set the tab close knob to a day?
