Fix WebDriverError
in Selenium
✅ Solution
WebDriverError in Selenium often indicates a mismatch between the browser driver version (e.g., ChromeDriver, GeckoDriver) and the browser version installed on your system. Ensure that you download and use the correct driver version corresponding to your browser's version, and that the driver executable is properly placed in your system's PATH or specified in your Selenium code. Also, verify that your browser installation is not corrupted or inaccessible, and that your profile exists.
