Following a crash, Brave only displays about half of the windows that had been open (not counting any Private or Private with TOR windows, which would not be expected to reopen).
A tab manager extension I use (TABLI) displays all of the missing windows and tabs – so they are ‘there’ but don’t display in the browser or appear in the Window dropdown menu.
Not the first time I’ve posted about this.
