I have a program that tests some of our sites with javascript disabled. It worked well, until we updated from WebDriver 2.4.5 to the latest. Now I get this error:
java.lang.IllegalArgumentException: Preference javascript.enabled may not be overridden: frozen value=true, requested value=false
It looks like the argument to disable JS is no longer allowed. I can't downgrade the WebDriver because the earlier versions don't work correctly with our updated Firefox.
What are my options for testing with JS disabled? I know Chrome never worked before, and now Firefox doesn't. I tried searching for "webdriver js disabled" but the results just bring back the javascript.enabled, false argument that no longer seems to work.
Best I could come up with is;
Create a new Firefox profile called NoJs by starting it with -P
Go to about:config and disable javascript there
Use this profile in selenium
ProfilesIni allProfiles = new ProfilesIni();
FirefoxProfile profile = allProfiles.getProfile("NoJs");
WebDriver driver = new FirefoxDriver(profile);

I have some issue with selenium-webdrivers on Ubuntu. Everything is working fine instead firefox has no javascript activated. When I open a website that requires javascript it pop the noscipt error. So the website is displaying <noscript>Javascript is required ....
Is there a function to enable JS on Firefox on Ubuntu or das this is a selenium failure and I need to set a driver.
Code:
require 'rubygems'
require 'headless'
require 'selenium-webdriver'
#headless = Headless.new
#headless.start
#driver = Selenium::WebDriver.for :firefox
#driver.navigate.to 'URL'
... actions
#headless.destroy
The Website navigate over HTTP:Headers and Ajax I think.
If someone have an idea I would be thankful.
On dev machine (win 10) all working fine.
Regards
Mat
EDIT
With recent modules you need firefox 65+, because firefox 65+ has his own headless module. Now everything is working fine and fast. Also need recent Geckodriver. Poorly not working with old firefox versions.
Refer comment here...
An alternative is to install a Firefox addon that disables JavaScript. This worked for me with Firefox 45 ESR, selenium-webdriver (2.53.4), and capybara (2.8.1):
profile.add_extension(File.expand_path('../quickjava-2.1.0-fx.xpi', FILE))
Configure the extension to disable JavaScript by default.
profile['extensions.thatoneguydotnet.QuickJava.startupStatus.JavaScript'] = 2
Disable loading the extension's first-run tab.
profile['extensions.thatoneguydotnet.QuickJava.curVersion'] = '2.1.0'

How do i set up a custom protocol handler in chrome? Something like:
myprotocol://testfile
I would need this to send a request to http://example.com?query=testfile, then send the httpresponse to my extension.
The following method registers an application to a URI Scheme. So, you can use mycustproto: in your HTML code to trigger a local application. It works on a Google Chrome Version 51.0.2704.79 m (64-bit).
I mainly used this method for printing document silently without the print dialog popping up. The result is pretty good and is a seamless solution to integrate the external application with the browser.
HTML code (simple):
Click Me
HTML code (alternative):
<input id="DealerName" />
<button id="PrintBtn"></button>
$('#PrintBtn').on('click', function(event){
event.preventDefault();
window.location.href = 'mycustproto:dealer ' + $('#DealerName').val();
});
URI Scheme will look like this:
You can create the URI Scheme manually in registry, or run the "mycustproto.reg" file (see below).
HKEY_CURRENT_USER\Software\Classes
mycustproto
(Default) = "URL:MyCustProto Protocol"
URL Protocol = ""
DefaultIcon
(Default) = "myprogram.exe,1"
shell
open
command
(Default) = "C:\Program Files\MyProgram\myprogram.exe" "%1"
mycustproto.reg example:
Windows Registry Editor Version 5.00
[HKEY_CURRENT_USER\Software\Classes\mycustproto]
"URL Protocol"="\"\""
#="\"URL:MyCustProto Protocol\""
[HKEY_CURRENT_USER\Software\Classes\mycustproto\DefaultIcon]
#="\"mycustproto.exe,1\""
[HKEY_CURRENT_USER\Software\Classes\mycustproto\shell]
[HKEY_CURRENT_USER\Software\Classes\mycustproto\shell\open]
[HKEY_CURRENT_USER\Software\Classes\mycustproto\shell\open\command]
#="\"C:\\Program Files\\MyProgram\\myprogram.exe\" \"%1\""
C# console application - myprogram.exe:
using System;
using System.Collections.Generic;
using System.Text;
namespace myprogram
{
class Program
{
static string ProcessInput(string s)
{
// TODO Verify and validate the input
// string as appropriate for your application.
return s;
}
static void Main(string[] args)
{
Console.WriteLine("Raw command-line: \n\t" + Environment.CommandLine);
Console.WriteLine("\n\nArguments:\n");
foreach (string s in args)
{
Console.WriteLine("\t" + ProcessInput(s));
}
Console.WriteLine("\nPress any key to continue...");
Console.ReadKey();
}
}
}
Try to run the program first to make sure the program has been placed in the correct path:
cmd> "C:\Program Files\MyProgram\myprogram.exe" "mycustproto:Hello World"
Click the link on your HTML page:
You will see a warning window popup for the first time.
To reset the external protocol handler setting in Chrome:
If you have ever accepted the custom protocol in Chrome and would like to reset the setting, do this (currently, there is no UI in Chrome to change the setting):
Edit "Local State" this file under this path:
C:\Users\Username\AppData\Local\Google\Chrome\User Data\
or Simply go to:
%USERPROFILE%\AppData\Local\Google\Chrome\User Data\
Then, search for this string: protocol_handler
You will see the custom protocol from there.
Note: Please close your Google Chrome before editing the file. Otherwise, the change you have made will be overwritten by Chrome.
Reference:
https://msdn.microsoft.com/en-us/library/aa767914(v=vs.85).aspx
Chrome 13 now supports the navigator.registerProtocolHandler API. For example,
navigator.registerProtocolHandler(
'web+custom', 'http://example.com/rph?q=%s', 'My App');
Note that your protocol name has to start with web+, with a few exceptions for common ones (like mailto, etc). For more details, see: http://updates.html5rocks.com/2011/06/Registering-a-custom-protocol-handler
This question is old now, but there's been a recent update to Chrome (at least where packaged apps are concerned)...
http://developer.chrome.com/apps/manifest/url_handlers
and
https://github.com/GoogleChrome/chrome-extensions-samples/blob/e716678b67fd30a5876a552b9665e9f847d6d84b/apps/samples/url-handler/README.md
It allows you to register a handler for a URL (as long as you own it). Sadly no myprotocol:// but at least you can do http://myprotocol.mysite.com and can create a webpage there that points people to the app in the app store.
This is how I did it. Your app would need to install a few reg keys on installation, then in any browser you can just link to foo:\anythingHere.txt and it will open your app and pass it that value.
This is not my code, just something I found on the web when searching the same question. Just change all "foo" in the text below to the protocol name you want and change the path to your exe as well.
(put this in to a text file as save as foo.reg on your desktop, then double click it to install the keys)
-----Below this line goes into the .reg file (NOT including this line)------
REGEDIT4
[HKEY_CLASSES_ROOT\foo]
#="URL:foo Protocol"
"URL Protocol"=""
[HKEY_CLASSES_ROOT\foo\shell]
[HKEY_CLASSES_ROOT\foo\shell\open]
[HKEY_CLASSES_ROOT\foo\shell\open\command]
#="\"C:\\Program Files (x86)\\Notepad++\\notepad++.exe\" \"%1\""
Not sure whether this is the right place for my answer, but as I found very few helpful threads and this was one of them, I am posting my solution here.
Problem: I wanted Linux Mint 19.2 Cinnamon to open Evolution when clicking on mailto links in Chromium. Gmail was registered as default handler in chrome://settings/handlers and I could not choose any other handler.
Solution:
Use the xdg-settings in the console
xdg-settings set default-url-scheme-handler mailto org.gnome.Evolution.desktop
Solution was found here https://alt.os.linux.ubuntu.narkive.com/U3Gy7inF/kubuntu-mailto-links-in-chrome-doesn-t-open-evolution and adapted for my case.
I've found the solution by Jun Hsieh and MuffinMan generally works when it comes to clicking links on pages in Chrome or pasting into the URL bar, but it doesn't seem to work in a specific case of passing the string on the command line.
For example, both of the following commands open a blank Chrome window which then does nothing.
"c:\Program Files (x86)\Google\Chrome\Application\chrome.exe" "foo://C:/test.txt"
"c:\Program Files (x86)\Google\Chrome\Application\chrome.exe" --new-window "foo://C:/test.txt"
For comparison, feeding Chrome an http or https URL with either of these commands causes the web page to be opened.
This became apparent because one of our customers reported that clicking links for our product from a PDF being displayed within Adobe Reader fails to invoke our product when Chrome is the default browser. (It works fine with MSIE and Firefox as default, but not when either Chrome or Edge are default.)
I'm guessing that instead of just telling Windows to invoke the URL and letting Windows figure things out, the Adobe product is finding the default browser, which is Chrome in this case, and then passing the URL on the command line.
I'd be interested if anyone knows of Chrome security or other settings which might be relevant here so that Chrome will fully handle a protocol handler, even if it's provided via the command line. I've been looking but so far haven't found anything.
I've been testing this against Chrome 88.0.4324.182.
open
C:\Users\<Username>\AppData\Local\Google\Chrome\User Data\Default
open Preferences then search for excluded_schemes you will find it in 'protocol_handler' delete this excluded scheme(s) to reset chrome to open url with default application
I am running my test in Visual Studio 10, with C# and Selenium. There is a moment that Im landing on a page and I need to check some elements of the page, but its like "loading" continuously so its impossible to find this elements, cause are changing. The only way to find them is in Chrome Settings, Disable JavaScript and perfect it works. But how I disable Javascript with selenium in the same page, without call a new one? Just refreshing or smthg. Thx!!!

You can set that to profiler. Handling would be different based on how you want to do it
var firefoxProfile = new FirefoxProfile();
firefoxProfile.setPreference("javascript.enabled", false);
See this
For Chrome
DesiredCapabilities caps = DesiredCapabilities.chrome();
caps.setCapability("chrome.switches", Arrays.asList("--disable-javascript"));
Taken from here
I have a simple test using the selenium-webdriver javascript package that finds a text field by name and enters text. The test runs fine in Firefox and Chrome, but fails in Phantomjs. I also tried finding the element by xpath and id, but it keeps failing in Phantomjs. Has anyone had a similar experience and could point me in the right direction for debugging?
Thanks
I was facing same issue. In my case, problem was that we have self signed certificate on our test server. I found solution here: phantomjs-and-self-signed-certificates
You have to set desired capabilities for your driver:
DesiredCapabilities dCaps = new DesiredCapabilities();
dCaps.setJavascriptEnabled(true);
dCaps.setCapability(PhantomJSDriverService.PHANTOMJS_CLI_ARGS, new String[]{"--web-security=no", "--ignore-ssl-errors=yes"});
dCaps.setJavascriptEnabled(true);
driver = new PhantomJSDriver(dCaps);
To ignore self signed certificates set "--ignore-ssl-errors=yes"
I am getting (NS_ERROR_DOCUMENT_NOT_CACHED) error when I try to access the Javascript code through firefox.I get this error in the contents tab of HTTPFOX.
I googled and set the parameters of browser in config file as specified in this site but it still doesn't work.
http://code.google.com/p/httpfox/issues/detail?id=20
Can somebody suggest whats going wrong since the same code works fine for safari browser..
If anyone is interested in a solution to this, I believe it's to do with the plugin noscript. Disabling it fixed this, but I have yet to work out what part of noscript was causing the issue. Will update if I find out.
Edit:My issues was with a twitter auth callback. In the Advanced settings of noscript under ABE, in the SYSTEM ruleset, on the line "Accept from LOCAL" I added "*.twitter.com". This allowed callback requests from *twitter.com to return to a local address.
On my macbook I had to uninstall firefox completely to correctly get the content of an ajax response with httpfox. This also implies to remove the firefox profile bij removing this Firefox folder (I could only find it via the terminal and not via Finder):
/Users/<YOURUSER>/Library/Application Support/Firefox
Then install firefox again and install the httpfox add-on.
I tried many cache settings also by entering about:config in the firefox URL however without succes. Be aware that removing the profile settings like I describe will also remove all your personal firefox customization. It concerned firefox 18.0.2 and httpfox 0.8.11.
We used to get the same error when our JavaScript made an XMLHTTPRequest to the server. On the server side, we had java, and the java response, the content type was not explicitly set to "text/html". When that was done
resp.setContentType("text/html");
the error went away.
