[🐛 Bug]: Unable to load crx extension in Chrome 142

[lupanlpb]

Description

It is impossible to load Chrome crx extension in Chrome 142, while same code works well before Chrome upgrade.

Reproducible Code

options = webdriver.ChromeOptions()
        extension_path = os.path.join(project_dir, "extensions/ModHeader-Modify-HTTP-headers-Chrome-Web-Store.crx")
        options.add_extension(extension_path)
        options.add_argument("--test-type")
        options.add_argument("--start-maximized")
        options.add_argument("--disable-web-security")
        options.add_argument("--allow-insecure-localhost")
        options.add_argument("--allow-running-insecure-content")
        options.add_argument("--disable-site-isolation-trials")
        options.add_argument("--lang=en")
        options.add_argument("--disable-features=DisableLoadExtensionCommandLineSwitch")
        _driver = webdriver.Chrome(options)

They probably disabled the --disable-features=DisableLoadExtensionCommandLineSwitch flag.

They probably disabled the --disable-features=DisableLoadExtensionCommandLineSwitch flag.

@cgoldberg So what should I do to load the crx plugin now？

i've been using the workaround (for java) in #15788 since Chrome 137 to add extensions to Chrome.
but this workaround stopped working since Chrome 142.
--disable-features=DisableLoadExtensionCommandLineSwitch

is there a different workaround for this, or is adding extensions to Chrome not working anymore? has anyone managed to get this working for Chrome 142 onwards?
