@olesiak No, I didn't make any additional steps before and had no other windows open. I just tried it again with a new standalone installation of version 76.0.4017.123 on a HDD it's still the same. The open tabs are also visible in 'Search in tabs'.

@olesiak: 76.0.4017.123

In the thread of "76.0.4017.107 stable" Olesia Kastornova asked for a video for the Recently Closed Tabs problem,
"can you please share a video of the problem with us?"

Opera "search tabs" don't show the recently closed tabs in Windows 10.
Opera is installed as standalone, this is happening beyond version 75.0.3969.218.

"Search in tabs" doesn't always show closed tabs started from the search box on the Speed Dial page, while the extension "Undo Closed Tabs Button" does.

https://earthobservatory.nasa.gov/ linked from within speed dial sometimes freezes Opera and Windows 10. Can someone confirm this?
