I am looking to disable images in Firefox when using Selenium. It should be a simple update of the preferences in firefox, which is documented on the instructions on Disable images in Selenium Python
However when i run, images display, and when i enter about:config, the value for permissions.default.image is still 1, rather than 2 which i have tried setting it to.
My code (written in Python) is:
from selenium import webdriver
firefox_profile = webdriver.FirefoxProfile()
firefox_profile.set_preference("permissions.default.image", 2)
driver = webdriver.Firefox(firefox_profile)
driver.get(web_address)
For reference, this code works perfect with another change to preference e.g. turning off csv files with the line firefox_profile.set_preference("permissions.default.stylesheet",2). The only difference i can tell between the csv setting and the image one, is that the line permissions.default.image already exists in about:config (i.e. without me setting it), however the line permissions.default.stylesheet does not. ... it seems that i can add new lines in with the value i want, but not change an existing one (or it is beein over-ridden by Selenium after i enter my value).
From what I understand, this problem is related to the following Firefox issues:
Remove "Load images automatically" checkbox from Prefs
Get rid of options that kill our product
That means that permissions.default.image is frozen, cannot be changed and does nothing.
Alternatives:
use Image Block extension
switch to Chrome (Disable images in Selenium ChromeDriver)
I had this problem. the solution is bellow in 3 steps.
1- creating new profile for Firefox. in Windows completely close Firefox. press (Window+R) , write firefox.exe -p then press enter and create a new profile.
2-open Firefox with the created profile then open about:config in navigation bar and find permissions.default.image and make it's number 2.
3-change your code like bellow
ProfilesIni profile = new ProfilesIni();
FirefoxProfile myprofile = profile.getProfile("your_profile_name");
WebDriver driver = new FirefoxDriver(myprofile);
I've created a code sample for disabling images.
#DISABLE IMAGES ON FIREFOX
def disable_images(driver):
driver.get("about:config")
driver.find_element("id","warningButton").click()
searchArea=driver.find_element("id","about-config-search")
searchArea.send_keys("permissions.default.image")
editButton=driver.find_element("xpath","/html/body/table/tr[1]/td[2]/button")
editButton.click()
editArea=driver.find_element("xpath","/html/body/table/tr[1]/td[1]/form/input")
editArea.send_keys("2")
saveButton=driver.find_element("xpath","/html/body/table/tr[1]/td[2]/button")
saveButton.click()

I am new to python selenium and I need more explanation on the effect of the below code on selenium Firefox profile.
profile.set_preference('browser.helperApps.neverAsk.saveToDisk', ('application/vnd.ms-excel'))
Firefox browser is by default asking if to save or to open the file when user tries to download a file.
To prevent Firefox opening that dialog we can predefine not to ask this for predefined types of files.
Each file type should be mentioned explicitly with such setting in order to not ask when downloading of such a kind of file initiated.
Basically when setting up your Firefox profile you add a call to set the property browser.helperApps.neverAsk.saveToDisk like this.
You won't face download pop up.
so basically it means that download any file and save it to the desired location using Selenium Webdriver.
I would like to create a new session for each tab I open and then control the sessions individually using Selenium python. Is this possible?
#reynoldsnp: Firefox has an official addon that does this, but I'm not sure if you can get selenium to interact with the addon. addons.mozilla.org/en-GB/firefox/addon/multi-account-containers If you figure out a way to do it, I would love to know how.
(I can't comment yet due to my reputation score, therefore quoted comment).
I don't know how to actually interact with the extension but if you have a known set of sites you would like to open:
Try this:
Make a firefox profile for your use with selenium. Multiple profiles
Windows 8/8.1/10:
Press Win + R on your keyboard.
Type firefox --new-instance --ProfileManager
Open Firefox in that profile by selecting the new profile in the setup wizard. Install the extension in that profile.
Set up the containers you would like in the extension, to, by default, open up with a specific site.
Ensure that the checkbox is ticked.
Start selenium with that profile like this:
from selenium import webdriver
profile = webdriver.FirefoxProfile('path/to/your/profile') # on windows found here: %APPDATA%/Mozilla/Firefox/Profiles
driver = webdriver.Firefox(firefox_profile=profile)
Navigate between tabs, effectively containers, using selenuium.
First, no, you cannot. While tabs runs as a process, they are attached to the session ID which initially open the browser. This is how the protocol works https://www.w3.org/TR/webdriver/#new-session
They have, however, a unique ID which you can use to identify them by and switch between them.
driver.window_handles
will give you the list of open tabs. Each tab is fully isolated. You can now choose between
driver.switch_to_window("any open tab taken from windows handles list")
driver.do_something
driver.switch_to_window("any other tab from windows handles list")
driver.do_something_else_on_other_tab
# or (this option can let you run in parallel)
driver a = ChromeDriver()
driver b = ChromeDriver()
a.do_something
b.do_something
As suggested (and I personally do myself) open new session for each tab you want, that way you can parallel them and run much faster, all in all.
I am not sure the performance difference is that significant between multiple browsers or multiple tabs... they should use almost the same resources.
I want to be able to use pure selenium webdriver to open a zoom link in Chrome and then redirect me to the zoom.us application.
When I execute this:
from selenium import webdriver
def main():
driver = webdriver.Chrome()
driver.get("https://zoom.us/j/000-000-000")
main()
I receive a pop-up saying
https://zoom.us wants to open this application.
and I must press a button titled open zoom.us to open the app.
Is there a way to press this pop-up button through selenium. Or, is there some other way to open zoom from chromedriver?
NOTE: I only want to use selenium. I have been able to implement pyautogui to click on the button but that is not what I am looking for.
Solution for Java:
driver.switchTo().alert().accept();
Solution for Python:
driver.switch_to.alert.accept()
There are a lot of duplicated questions regarding this issue. Here is one of them, and it is quite sure that selenium is not capable of achieving such job since it only interacts with the chrome page. I previously encountered this issue as well and here is my solution to it. It might look really unprofessional, but fortunately it works.
The logic of my solution is to change the setting of chrome in order to skip the popup and directly open the application you want. However, the Chrome team has removed this feature in the latter version for some reasons, and we need to get it back manually. Then, we know that everytime when selenium starts to do the thing it opens a new Chrome page with NO customized settings just like the incognito page. Therefore we need to do something to let selenium opened a Chrome page with your customized setting, so that we can make sure that the popup, which we changed manually to skip, can be skipped successfully.
Type the following code in your terminal.
defaults write com.google.Chrome ExternalProtocolDialogShowAlwaysOpenCheckbox -bool true
This enables you to change the setting of skipping popups, which is the feature Chrome team removed.
Restart Chrome,and open the zoom (or whatever application) page to let the popup display. If you do the 1st step correctly you will be able to see there is a checkbox shown next to the "Open Zoom.us" saying if you check it chrome will open this application without asking, that is, to skip the popup for this application.
Now we need to let selenium open the Chrome with our customized setting. To do this, type "chrome://version" in the search tab of your ordinary Chrome (Not automated page opened by selenium). Go to "Profile Path", and copy this path without the last word "default". For example:
/Users/MYNAME/Library/Application Support/Google/Chrome/Default
This is my profile path, but I only copy everything except the last word Default, so this is what I need to copy.
/Users/MYNAME/Library/Application Support/Google/Chrome/
This is for Mac users, but for Windows only the path is different(starts with C:// or something), steps are same.
from selenium import webdriver
from selenium.webdriver.common.keys import Keys
from selenium.webdriver.chrome.options import Options
option = Options()
option.add_argument('THE PATH YOU JUST COPIED')
driver = webdriver.Chrome(executable_path='YOUR PATH TO CHROMEDRIVER', options=option)
driver.get("google.com") #Or anything else
We use "options" to let selenium open a page with our customized profile. Now you will see selenium opens a Chrome page with all your account profile, settings, and it just appears like your ordinary chrome page.
Run your code. But before that, remember to quit ALL CHROME sessions manually. For Mac, make sure that there is no dot under Chrome icon indicating that Chrome is not running for any circumstances. THIS STEP IS CRITICAL otherwise selenium will open a chrome page and it just stops there.
Here are all the steps. Again, this solution is vert informal and I personally don't think it is a "solution" to this problem. I will try to figure out a better way of achieving this in the future. But I still posted this as an alternative simply because I guess it might be helpful to some extent for somebody just like me. Hope it works for you, and good luck.
When I use selenium webdriver with a custom firefox profile I get the firefox Add-ons pop up showing 2 extensions: Firefx WebDriver 2.5.0 and Ubuntu Firefox Modifications 0.9rc2.
How can I get rid of this popup? I looked in the server jar to see if I could find the extensions, no luck. Looked online for the extensions, no luck. When I run the code without using the custom profile there is no popup.
You need to add an entry called extensions.newAddons to the profile's preferences and set the value to false.
Start firefox with the custom profile
firefox -profile <path to profile directory>
Type about:config in the address bar and press the enter key. Right-click the preference pane to open the context menu and go to New -> Boolean.
Enter extensions.newAddons for the preference name. Select false for the new boolean value.
The entry should prevent the new addon window from appearing when you start Firefox with that profile.
Open Firefox with this profile (with profile manager), go to Firefox preferences, turn off updates - this works for me.
I'm experimenting with Firefox's WebDriver and I'd like to ask if it is possible to handle "Download" window (to accept or decline incoming download request)?
For example, simple piece of code:
import selenium.firefox.webdriver
dr = selenium.firefox.webdriver.WebDriver()
# Firefox is showed up.
# Let's say I'd want to download python.
dr.get('http://python.org/ftp/python/3.1.3/python-3.1.3.msi')
# Download window is showed up.
# How could I accept the download request?
# As I understand, the method below should return
# two handles but I get only main window's handle.
handles = dr.get_window_handles()
# Seems like WebDriver cannot "see" this popup.
I've experimented with this a little bit but haven't found the solution yet. I'd really appreciate any hint.
Many thanks,

One solution to this is changing WebDriver's Firefox profile to automatically download some MIME types to a given directory.
I'm not sure how (or if) this is exposed in Python, but it's mentioned on the Ruby bindings page on the Selenium wiki (under "Tweaking Firefox preferences").
I don't think that this is the sort of thing that WebDriver was built for, but I'll take a crack at it. There is nothing built into the Firefox WebDriver to handle this specific case, but there are a few approaches you may take.
You can open FF with the profile that your WebDriver script uses and edit the preferences to always save the file instead of asking (Options > Applications > Windows Installer Package - set to "Save File"). Now, however, there's no way to tell that the file is downloading from the browser unless you get redirected to a 404 page. If not, you can check if the file exists in the Downloads directory for the same profile (Options > Main > Donwloads). If it's still in the process of downloading, the filename will be WhateverFileName.ext.part
Your other option is to use the non-visual HTMLUnit driver, navigate to the download link, click it, and the get the page source (will be the contents of the file). This works with textual files, I can't guarantee that it will work similarly for binaries, nor do I know how it will be encoded in such a case.
Best of luck
i came across this when i was trying to download a file using capybara
and got halted by the download prompt
SeleniumHQ : Selenium WebDriver
profile = Selenium::WebDriver::Firefox::Profile.new
profile['browser.download.dir'] = "/Downloads"
profile['browser.download.folderList'] = 2
profile['browser.helperApps.neverAsk.saveToDisk'] = "audio/wav"
driver = Selenium::WebDriver.for :firefox, :profile => profile
driver.navigate.to('http://www.address.com/file.wav')
this just downloads the file into the directory specified, no prompt :)
the other option that i came across was
Determining file MIME types to autosave using Firefox & Watir-WebDriver
i have tried watir before and it proved very useful
