为什么 Firefox selenium webdriver 不能处理超过 20 个选项卡？

Question

我使用以下脚本将我的 png 图像上传到一个秘密网站：

from selenium import webdriver
from selenium.webdriver.common.by import By
from selenium.webdriver.support.ui import WebDriverWait
from selenium.webdriver.support import expected_conditions as EC
import time
import os

def select_image_for_tab(driver, image_file):
    # Find and click on "Browse for a file" button
    browse_button = driver.find_element(By.XPATH, "//button[text()='Browse for a file']")
    browse_button.click()

    # Wait for the file input to be visible and interactable
    time.sleep(0.5)

    # Handle the file upload dialog using Selenium
    file_input = driver.find_element(By.XPATH, "//input[@type='file']")
    file_input.send_keys(image_file)

    # Wait for the file to be uploaded and the file selection dialog to close
    WebDriverWait(driver, 20).until(EC.invisibility_of_element_located((By.XPATH, "//input[@type='file']")))

if __name__ == "__main__":
    image_files_directory = r"E:\Desktop\social\Output_folder\folder 20"

    # Prompt to focus on Firefox
    print("Please focus on Firefox. The script will start in 5 seconds...")
    time.sleep(5)

    # Set up the Firefox driver
    driver = webdriver.Firefox()

    try:
        # Open the website in a new tab
        driver.get("UPLOAD_URL.com")

        # Wait for the website to load and the target element to be clickable
        WebDriverWait(driver, 10).until(EC.presence_of_element_located((By.XPATH, "(//div[@class='ms-Stack css-147']//div)[1]")))

        # Click on the target element
        target_element = driver.find_element(By.XPATH, "(//div[@class='ms-Stack css-147']//div)[1]")
        target_element.click()

        # Get a list of all PNG image files in the directory
        image_files = [f for f in os.listdir(image_files_directory) if f.lower().endswith('.png')]

        # Select image files for each tab
        for image_file in image_files:
            select_image_for_tab(driver, os.path.join(image_files_directory, image_file))
            time.sleep(0.5)  # Adjust this delay if needed

            # Open a new tab and load the website in it
            driver.execute_script("window.open('about:blank');")
            driver.switch_to.window(driver.window_handles[-1])
            driver.get("UPLOAD_URL.com")

            # Wait for the website to load in the new tab and the target element to be clickable
            WebDriverWait(driver, 10).until(EC.presence_of_element_located((By.XPATH, "(//div[@class='ms-Stack css-147']//div)[1]")))

            time.sleep(4)  # Additional wait time if needed

        print("File selection completed for all tabs.")
    except Exception as e:
        print("An error occurred:", e)
    finally:
        # The script will not close the browser or any tabs after completion
        pass

但每次我都必须将文件分成 20 个一组。
Firefox 无法处理超过 20 个选项卡。如何在远程 Firefox 中绕过此限制？

请注意：请不要询问秘密 URL 或 UPLOAD_URL.com

Answer 1

不需要答案，我找到了解决方案。
我必须使用

dom.popup_maximum

将

opts.set_preference("dom.popup_maximum", 50)

首选项设置为 50。然后我在使用

opts

初始化

webdriver.Firefox()

时必须使用

driver = webdriver.Firefox(options=opts)

。
这允许 Firefox 一次处理最多 50 个弹出窗口（选项卡），这应该允许您在脚本中处理大量图像，而不会达到最大选项卡限制。
