IE9, Selenium: how to disable download prompting bar ? - testing

I need, for testing purpose, to disable download prompting bar in IE9 (that asks for opening or saving the file), otherwise I cannot test a feature of my app that lets to download a file.
There are download managers that allow to do it, I am wondering where I may put my hands (which Window's registry) in order to remove this download prompting bar.


You can try to switch to new window and close it or execute following code.
driver.switchTo().alert().dismiss();


You don't say which language you are using, but I was able to do this using the following Ruby code.
Note that it does not touch the registry, as asked in your question, but uses the keyboard to interact with the IE9 download bar. It does not disable the download bar altogether, but effectively does the same thing by getting IE to save the file once a download has been invoked.
Selenium can't see the IE9 download bar, so you can't interact with it using Selenium.
require 'win32ole'
#assuming download has started, and IE9 download window is now visible
if $browser = "IE" then
wsh = WIN32OLE.new('Wscript.Shell')
wsh.AppActivate('My webpage - Windows Internet Explorer')
sleep 1
wsh.SendKeys('%s;') # $browser.send_keys #doesn't work - because IE download window is not on the web page.
end

Firefox Ignores Content-Disposition

I'm trying to write MVC endpoint that will optionally set the content-disposition to inline or attachment in order to either display the file (a pdf) inside a new browser tab or else to download it. The UI allows the user to select how they'd like to open the file (not my design - can't change that aspect of it).
Note that this works in Chrome/Edge just as expected.
In Firefox, the application settings for PDF appear to trump the content-disposition. Is there a reliable way to get Firefox to respect the content-disposition? Preferably a way that will work w/ a vanilla installation of the browser such that end-users don't need to make any modifications on their end for it to work.
Here's the code I'm using to setup my response (class is derived from ApiController):
var response = Request.CreateResponse(System.Net.HttpStatusCode.OK);
response.Content = new PushStreamContent((stream, content, context) =>
{
dispatcher.Dispatch(request, stream);
}, new MediaTypeHeaderValue(MediaTypeNames.Application.Pdf));
response.Content.Headers.ContentDisposition = new ContentDispositionHeaderValue(contentDisposition)
{
FileName = $"{auto_generated_fileName}.pdf",
};
response.Headers.CacheControl = new CacheControlHeaderValue()
{
NoCache = true,
NoStore = true
};
return response;

We have noticed this issue in our webapp as well. The webapp has a download button that lets the user download a PDF file. Firefox shows the PDF file in the current tab, which effectively kills the webapp.
After a bit of research, this appears to be an intentional feature, see the release notes for Firefox 98:
When you set an application to open files of a specific type in your Firefox preference settings, those files will open automatically, even files served by the website with "content-disposition: attachment". The same applies to PDF files that are set to open in Firefox by default. This is a fix to bug 453455.
Personally, while I can understand some users may want this for web pages that don't behave well, this is an issue for well-behaved web apps.
Setting the download attribute on the anchor does not appear to work either, Firefox still shows the file inline (tested with Firefox 99.0)
So as far as I am aware, you cannot force the browser to download the file if the browser does not allow it. Other web apps such as OwnCloud or Google Drive are having the same issue -- if you click right on a PDF file in Google Drive and then click on Dowload, Firefox still open the PDF file inline, whereas Chrome downloads it.
For now, it seems the best you can do is to open file in a new tab, to prevent the webapp or web page from being replaced by the downloaded file (which is also what Google Drive seems to be doing). You can open the download in a new tab or window e.g. via the target attribute on an <a> links or via the formtarget atttribute on a <button> element.

I found #blutorange's answer after trying to find a solution to the same problem as OP. However, just before I got here, I stumbled across this answer from back in 2013 - https://stackoverflow.com/a/16515146 which suggests to set the Content-Type header to application/octet-stream, instead of application/pdf.
I tried that solution and what do you know - it works! The PDF opens in a new tab in Firefox automatically, but at least it doesn't replace the tab of my application, so yay! Chrome doesn't seem to mind it either and my PDF viewer on my computer also recognizes the files as PDFs.
Now, this might not be the most "correct" fix to the issue we're facing, but it's an alternative to forcing open a new tab.

File Upload warning Chrome 66 and above to be handled using Selenium Webdriver

Chrome browser allows folder upload (using browse dialog) and recently post version 65 we are seeing a security popup which states that do you trust this site for uploading the files from folder.
This popup is causing the Automation to fail, is there any way to handle it using Selenium? like by using certain capability to bypass it or clicking it?
I already tried Alert accept/dismiss but it doesn't work as it seems that its not an alert. I also tried UIAutomation but it seems that elements are enclosed within the browser without any classname/ID's.
For the time being I have given a workaround of sending Keyboard Tab key and Enter keys.
Is there a proper way to bypass this dialog?
Any help will be appreciated.

Saucelabs tests block on browser allow dialog

My web app uses IndexedDB and I'm testing on SauceLabs. Some months back my tests ran but now they block on a browser dialog that says "http://gbserver3.cs.unc.edu/" wants to: store files on this device", with an Allow button.
This is Win7 and Chrome or Firefox. Likely others too.
How can I dismiss or prevent this dialog?
Update: I have discovered that if I don't ask for quota I don't get the popup and my tests succeed. I'd still like to learn how to get rid of that dialog.

we are using Nightwatch.js in our project and we were facing the same issue.
What actually did the trick was using --unlimited-storage switch when launching the browser.

IE 10 not using AppCache after browser closed

I wrote an application using the HTML5 Cache Manifest and I'm having a problem using it in IE 10.
I used Fiddler to witness the manifest file being downloaded and all resources fetched on the initial load of the application. If I disable my network adapter to force the machine offline, the application continues to work as expected as long as I don't close the browser window.
However, when I close the browser window, then attempt to re-open the page from a favorite, IE 10 tells me "You're not connected to a network". Obviously I know that, I'm trying to use the app offline. These exact steps work in Chrome.
Is this behavior by design? Is there a workaround? I can't test with IE 11 right now...is this different in IE 11?

Hearing of some issues of the appcache clearing if your company utilizes gpo settings and has "empty temporary internet files folder when browser is closed" enabled.

Did you find the answer to this? I have the same problem. I did get a bit further though. I found that if you go to the IE10 File menu option and tick Work Offline then try and access your cached app it loads the page but I still have an issue as it does not appear to be using the javascript file that should also be cached. All works ok on Google Chrome but our clients are restricted to IE so Chrome is not an option.

How do I enable popups in a new Firefox profile using selenium webdriver (Java)

The application I am testing requires pop-up to be enabled. When a launch a new Firefox profile I get the browser message
Firefox prevented this site from opening a pop-up window
with a button on the right called Options. I can manually click the Options button and select to Allow popups from ....
Question is how can I use profile.setPreference to set to allow popups from my website and also not show this Firefox message?

You can save your current Firefox prifile with allowed popups and load it from file like in this case: https://stackoverflow.com/a/6830109/1165331
save you current working profile with popups via browser and loat it.
