Safari tabs are not working properly for me. When I click Merge All Windows, the tabs I am merging disappear and instead I see blank tabs.
Also, sometimes when I've dragged a tab to move it out of a window with others, the tab shows up in two places: the new window and the old one. When I close the old one it makes the new one blank.
I believe this started with Safari 16.0. Experiencing this on macOS Monterey 12.6
I have this issue too, starting from Safari 16.0.
Also, sometimes when I move a tab from one window to another, the moved tab simply disappears. If I open the sidebar and check the tabs, the tab is still listed there. However it cannot be opened or moved. Opening a new tab or closing another tab clears this "ghost tab" from the sidebar.
I had the same issue as you with creating a "ghost tab" of the one I moved, except it stayed in the window.
I contacted Apple Support about my first issue. They suggested booting in Safe Mode to see if I can replicate the issue. Before I did that, I turned off all extensions and wasn't able to reproduce it. I'm going to turn on one extension at a time to see if I can narrow down which one could be causing this issue. I'll edit this or reply again if I'm able to reproduce this again.
When I move a tab out of a window with 2+ tabs. it simply disappears, and doesn't become its own window - REALLY ANNOYING. APPLE?? This is new as of the most recent update (v. 16.0)
Safari 16.0 tabs disappear when merged macOS
