Selenium new tab in Thread

Question

I have to process 20 sites at the same time using Selenium

class ThreadWithReturnValue(object):
    def __init__(self, target=None, args=(), **kwargs):
       self._que = queue.Queue()
       self._t = Thread(target=lambda q,arg1,kwargs1: q.put(target(*arg1, **kwargs1)), args=(self._que, args, kwargs), )
       self._t.start()

    def join(self):
       self._t.join()
       return self._que.get()

class Some_Class:
  def threads_setup(self,)
    for link in links[:20]:
      single_thread = ThreadWithReturnValue(target=self.core, args=(link, ))
      ALL_THREADS.append(single_thread)
       
    for thread in ALL_THREADS:
      result = thread.join()

  def core(self, link):
    # i must open new tab and work with him
    self.driver.get(link) 
    return some_value

If i work with

self.driver.execute_script("window.open()")

then all threads start to work for me only in the last tab

I would like each thread to work with a separate tab at the same time

How can I do it?

P.S class ThreadWithReturnValue i found in here
