    The google logo come form the css, where the pictures are embedded in the HTML as data (img src="data:image/jpeg;base64, ....) the code disable the loading of remote images not this type of sources

    • permissions.default.stylesheet: disable any formatting

    • permissions.default.image: disable any image and css background-image

    if the image is embedded into the page as base64 encoded is not blocked by these permissions because is part of the HTML code (see http://en.wikipedia.org/wiki/Data_URI_scheme)

    to disable more formatting you should add:

    • firefox_profile.set_preference("permissions.default.script", 2);
    • firefox_profile.set_preference("javascript.enabled", False);

    run the following javascript through the selenium script executor

    var queries = ['link[rel=stylesheet][href]', 'style'];
    for (var i = 0; i < queries.length; i++) {
        var remove = document.querySelectorAll(queries[i]);
        for (var j = 0; j < remove.length; j++) {
            remove[j].outerHTML = '';
        }
    }
    var inline = document.querySelectorAll('*[style]');
    for (var i = 0; i < inline.length; i++) {
        inline[i].removeAttribute('style');
    }
    

    I have tested this with google, it works. got the above script from this firefox extension code

    driver = webdriver.Firefox(firefox_profile)
    driver.get('http://www.google.com/')
    driver.execute_script("<put the above javascript here as string>")
