How do I set pass ChromeOptions using Driver(uc=True)

from seleniumbase import Driver
from sbvirtualdisplay import Display
from selenium import webdriver
chrome_options = webdriver.ChromeOptions()

prefs = {"profile.managed_default_content_settings.images": 2}
chrome_options.add_experimental_option("prefs", prefs)

with Display(visible=0, size=(1440, 1880)):

    driver = Driver(
        uc=True, 
        browser='chrome',
        cap_string=chrome_options.to_capabilities()
    )
    driver.get('https://www.website.com/')

This code is to proof that these ChromeOptions are not being passed because website is still loading images.

[mdmintz]

Options are passed directly into the Driver() on initialization:

SeleniumBase/seleniumbase/plugins/driver_manager.py

Line 65 in 77ee514

def Driver(

For example, there's already an option to block images with block_images=True:

SeleniumBase/seleniumbase/core/browser_launcher.py

Line 814 in 77ee514

prefs["profile.managed_default_content_settings.images"] = 2

cap_string is only for Selenium Grid use with compatible grids. And the Selenium Grid isn't compatible with UC Mode, which means you can't use cap_string with UC Mode either.

Hi! The argument of maximize= True does not work

[mdmintz]

Window maximization is done after the browser is launched:

driver.maximize_window()

[joako233]

I have this error, thanks.

[mdmintz]

There's no maximize=True option for Driver() initialization.

You have to use driver.maximize_window() after the browser is launched.

[joako233]

Okay, thanks! I have another question.I want to know which browser arguments such as chromium_arg = "--lang-en" are added by default in SeleniumBase, since, as you told me, if I add the same argument twice, it can cause problems. Thanks again."

[mdmintz]

Search for them in seleniumbase/core/browser_launcher.py.
There are also a few specific UC Mode options set in seleniumbase/undetected/__init__.py

SeleniumBase creates the downloaded_files folder in the working directory where pytest is invoked. Any click-initiated downloads will go there. It's also used for any special files needed. It also holds lock files to prevent issues with multi-threading. The folder resets at the start of every new pytest run so that past test runs don't interfere with new ones. The folder is hard-coded there to prevent issues. And since the folder is reset at the start of new pytest runs, you wouldn't want to use any other existing folders for it.

There are lots of built-in test methods that are specially made for that folder, such as:

self.get_downloads_folder()

self.get_browser_downloads_folder()

self.get_path_of_downloaded_file(file)

self.is_downloaded_file_present(file)

self.delete_downloaded_file_if_present(file)
# Duplicates: self.delete_downloaded_file(file)

self.assert_downloaded_file(file)

self.get_downloaded_files(regex=None, browser=False)

self.get_data_from_downloaded_file(file, timeout=None, browser=False)

self.assert_data_in_downloaded_file(data, file, timeout=None, browser=False)

If you need files in a different folder, use Python os, sys, and shutil libraries for copying the files you need into a different folder after they get downloaded to the downloaded_files folder.

There's also a pytest command-line option to archive existing downloads instead of deleting them:

SeleniumBase/README.md

Line 673 in 570910c

--archive-downloads # (Archive old downloads instead of deleting them.)

(A copy of those downloads will go into a folder in the archived_files/ folder at the end of the pytest run.)

Hello @mdmintz , could you tell me whether it’s possible to disable downloads to the downloaded_files directory, or if it must be cleared manually?

[mdmintz]

I think you can change it via CDP at runtime: https://github.com/mdmintz/MyCDP/blob/c84873e3aa0ca64c59da19f1a7c2cdab7f68556d/mycdp/browser.py#L398

There are examples of making mycdp calls from SB, eg:

SeleniumBase/examples/cdp_mode/raw_mobile_gitlab.py

Lines 9 to 11 in 622998f

	loop.run_until_complete(
	tab.send(
	mycdp.emulation.set_device_metrics_override(

but you'll need to use the set_download_behavior method. I think it exists in the async format:

SeleniumBase/seleniumbase/undetected/cdp_driver/tab.py

Lines 1248 to 1250 in 622998f

	await self.send(
	cdp.browser.set_download_behavior(
	behavior="allow", download_path=str(path.resolve())

[estiven94ops]

Hi, is there any option for multiples downloads without navigator asking?
like prefs: "download.prompt_for_download": False,

[mdmintz]

You can already download multiple files without a prompt. For example:

from seleniumbase import SB

with SB(test=True) as sb:
    sb.open("https://pypi.org/project/sbvirtualdisplay/#files")
    for i in range(3):
        sb.click('div.card a[href*=".tar.gz"]')
        sb.sleep(2)

[estiven94ops]

thank you!

[estiven94ops]

Hi, how can I open as a safe browser to download any files like .xml? using from seleniumbase import Driver

[mdmintz]

SeleniumBase methods already include waits, so you don't need WebDriverWait.

Don't use execute_script() for clicking to download something.
Instead, use a regular click, eg. driver.click(selector) in SeleniumBase.

If that doesn't work, add --unsafely-treat-insecure-origin-as-secure=* into chromium_arg (replace * with the domain).
Reference: https://stackoverflow.com/questions/78057740/chrome-122-how-to-allow-insecure-content-insecure-download-blocked/78065424#78065424

[estiven94ops]

ok, I tried using driver = Driver(uc=True, chromium_arg="--unsafely-treat-insecure-origin-as-secure=*") or Driver(uc=True, chromium_arg="--disable-features=InsecureDownloadWarnings " ), but didn´t work.
I also changed the download to this: driver.click("#frmPrincipal\:tablaCompRecibidos\:0\:lnkXml"); In any case, the download continues to be blocked, with the same pop-up window appearing; another way to do it?

[mdmintz]

Did you replace * with the domain, as mentioned on StackOverflow? https://stackoverflow.com/a/78065424/7058266

This is not a SeleniumBase-specific issue, so if that StackOverflow solution didn't help, then there probably isn't more advice I can give you. Maybe it will work if you don't use UC Mode (if you don't need that).

[estiven94ops]

yes, I replaced it. I was trying to use UC: (https://github.com/seleniumbase/SeleniumBase/blob/master/help_docs/uc_mode.md) because the webSite has an anti-bot service; is there any other way to use SeleniumBase and open driver in UC mode that allow me to disable thats pop up window with prefs or chrome.options?. In the "Undetectable Automation 2 video" you have 3 ways to open the chrome driver

[mdmintz]

You could try all those ways. You can even try sb.download_file(file_url) to download the file directly if you know the URL, but that's all I can think of, and that: https://stackoverflow.com/a/78065424/7058266

[Pranoy1c]

Is there a way to disable videos when using SeleniumBase with SB in CDP mode? Something like this:

from selenium.webdriver import ChromeOptions
chrome_options = ChromeOptions()
chrome_options.add_experimental_option(
    "prefs",
    {
        "profile.managed_default_content_settings.videos": 2  # 2 = Block videos
    }
)

[mdmintz]

Block the specific content that you want to block, like in https://github.com/seleniumbase/SeleniumBase/blob/master/examples/cdp_mode/raw_req_sb.py

[erfanedaraby]

hi
how can i tell seleniumbase not to close the browser after end of running the code?

in selenium we do this:
from selenium.webdriver.edge.options import Options
the_option=Options()
the_option.add_experimental_option("detach", True)
driver=webdriver.Edge(options=the_option)
