To control Firefox on Android (LineageOS 23.2) with Python Selenium using Magisk root but without ADB, you face some fundamental limitations:
Selenium on Android typically requires ADB to interact with the device and launch browsers like Firefox. Even with root access via Magisk, Selenium's standard Android WebDriver (e.g., Appium or geckodriver) still relies on ADB for device communication and browser automation. There is no official, supported way to run Selenium directly on an Android device without ADB, even with root access.
Magisk root allows you to run commands as root on the device, but it does not replace ADB's role in enabling remote control or automation frameworks like Selenium. You can use root to modify system files or run local scripts, but Selenium itself is designed to work over ADB for device automation.
Alternative Approaches:
Summary:
As of now, there is no documented or supported method to use Selenium with Firefox on Android (even with Magisk root) without ADB. The standard workflow for Selenium on Android devices requires ADB for device communication and browser control.
If your goal is to avoid physical USB connections, you could use ADB over Wi-Fi, which still uses ADB but without a cable. Would you like guidance on setting up ADB over Wi-Fi with Magisk root?
