Opening multiple tabs seems forgotten now.
I guess it could be some sort of spam.
There's a manual workaround
- open dev console
- you'll see the list of tab URLs logged
- right click > store as global variable
- with
temp1 being the name of the variable, use the command temp1.join('\n')
- copy the output (= 1 URL per line)
- paste it in an extension that can open tabs for each URLs such as this one :
