https://addons.mozilla.org/en-US/firefox/addon/tabhunter/ https://addons.mozilla.org/en-US/firefox/addon/tabhunter/ Makes it simple to select all tabs and copy paste as url or url + title It's also snappy for filtering and jumping to tabs especially when using the hotkey, I've used it for years with regularly over 5k tabs.
