welcome back.
it’s going to be a slight hassle having to copy and paste URLs from all those windows,
You might find something on the Chrome addon store that allows you copy tabs urls, similar, but not quite as good as
https://addons.mozilla.org/en-US/firefox/addon/copy-tabs/ and you can import/open them with https://addons.mozilla.org/en-US/firefox/addon/open-tabs-from-clipboard/
Hope it helps.
