像开发人员工具扩展一样，如何从Selenium中的Firefox中删除所有CSS样式

Question

I'm aware this question has been asked before, the issue is that none of the solutions do the job quite the same as the Developer tools extension which is what I'm in need of. This is achieved by going into the WebDeveloper extension menu and clicking 'Disable all styling' in the css section.

I need the page to look like this for some automation.

Needed Format (No CSS styling at all)

The first solution is

from selenium.webdriver.firefox.firefox_profile import FirefoxProfile

def disableImages(self):
## get the Firefox profile object
firefoxProfile = FirefoxProfile()
## Disable CSS
firefoxProfile.set_preference('permissions.default.stylesheet', 2)
## Disable images
firefoxProfile.set_preference('permissions.default.image', 2)
## Disable Flash
firefoxProfile.set_preference('dom.ipc.plugins.enabled.libflashplayer.so',
                              'false')
## Set the modified profile while creating the browser object 
self.browserHandle = webdriver.Firefox(firefoxProfile)

However, this only removes some images and not everything as you can see below.

1st Solution

Then I found a script

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');
}

The full explanation of how it worked is on this answer Disable styling on Google Search with Selenium FirefoxDriver which still did not turn out the same.

2nd Solution

Any help would be greatly appreciated? Thanks in advance.

Answer 1

Seems you were pretty close.

I have added two additional preferences in addition to the set you have used and I am able to achieve the desired results ie get rid of all the CSS Styling within Firefox .

• Code Block:

   from selenium import webdriver firefoxProfile = webdriver.FirefoxProfile() firefoxProfile.set_preference('permissions.default.stylesheet', 2) firefoxProfile.set_preference('permissions.default.image', 2) firefoxProfile.set_preference('dom.ipc.plugins.enabled.libflashplayer.so', 'false') firefoxProfile.set_preference("permissions.default.script", 2); firefoxProfile.set_preference("javascript.enabled", False); browserHandle = webdriver.Firefox(firefox_profile=firefoxProfile, executable_path=r'C:\\Utility\\BrowserDrivers\\geckodriver.exe') browserHandle.get('https://play.google.com/store')
