Not that I know of. But you can configure Firefox to <a href="http://kb.mozillazine.org/File_types_and_download_actions" rel="noreferrer">automatically start the download and save the file</a> in a specific place. Your test could then check that the file actually arrived.

blocks|key|1495989|text|对于这个问题，我有一个解决方案，请检查代码：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1495990|FirefoxProfile+firefoxProfile+=+new+FirefoxProfile();

blocks|key|1281181|text|我遇到了同样的问题，但我找到了解决方案。我用和这个blog一样的方法做了。|type|unstyled|depth|inlineStyleRanges|entityRanges|offset|length|data|1281182|当然这是Java，我已经把它翻译成了Python：|1281183|fp+=+webdriver.FirefoxProfile()

I was stuck with the same problem, but I found a solution. I did it the same way as this <a href="http://watirmelon.com/2011/09/07/determining-file-mime-types-to-autosave-using-firefox-watir-webdriver/">blog</a> did. 

Of course this was Java, I've translated it to Python:

<pre><code>fp = webdriver.FirefoxProfile()

fp.set_preference("browser.download.folderList",2)
fp.set_preference("browser.download.manager.showWhenStarting",False)
fp.set_preference("browser.download.dir",getcwd())
fp.set_preference("browser.helperApps.neverAsk.saveToDisk","text/csv")

browser = webdriver.Firefox(firefox_profile=fp)
</code></pre>

In my example it was a CSV file. But when you need more, there are stored in the <code>~/.mozilla/$USER_PROFILE/mimeTypes.rdf</code>

blocks|key|1496053|text|大多数浏览器(在我的例子中是Firefox)默认情况下选择OK按钮。所以我设法用下面的代码解决了这个问题。它基本上会为您按enter键，然后文件就会被下载。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1496054|Robot+robot+=+new+Robot();

//+A+short+pause,+just+to+be+sure+that+OK+is+selected

Most browsers (in mine case Firefox) select the OK button by default. So I managed to solve this by using the following code. It basically presses enter for you and the file is downloaded.

<pre><code>Robot robot = new Robot();

// A short pause, just to be sure that OK is selected
Thread.sleep(3000);

robot.keyPress(KeyEvent.VK_ENTER);
robot.keyRelease(KeyEvent.VK_ENTER);
</code></pre>

blocks|key|1496197|text|我也面临着同样的问题。在我们的应用程序中，通过传递DesiredCapabilities创建了FireFox实例，如下所示|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1496198|driver+=+new+FirefoxDriver(capabilities);|code-block|syntax|javascript|1496199|根据其他人的建议，我做了如下修改|1496200|FirefoxProfile+firefoxProfile+=+new+FirefoxProfile();+++++

I was facing the same issue. 
In our application the instance of FireFox was created by passing the DesiredCapabilities as follows

<pre><code>driver = new FirefoxDriver(capabilities);
</code></pre>

Based on the suggestions by others, I did my changes as 

<pre><code>FirefoxProfile firefoxProfile = new FirefoxProfile(); 
firefoxProfile.setPreference("browser.helperApps.neverAsk.saveToDisk",
 "application/octet-stream");
driver = new FirefoxDrvier(firefoxProfile);
</code></pre>

This served the purpose but unfortunately my other automation tests started failing. And the reason was, I have removed the capabilities which were being passed earlier.

Some more browsing on net and found an alternate way. We can set the profile itself in the desired Capabilities.

So the new working code looks like

<pre><code>DesiredCapabilities capabilities = DesiredCapabilities.firefox();

// add more capabilities as per your need.
FirefoxProfile firefoxProfile = new FirefoxProfile(); 
firefoxProfile.setPreference("browser.helperApps.neverAsk.saveToDisk",
 "application/octet-stream");

// set the firefoxprofile as a capability
capabilities.setCapability(FirefoxDriver.PROFILE, firefoxProfile);
driver = new FirefoxDriver(capabilities);
</code></pre>

blocks|key|1495836|text|不知道，但你也许可以检查一个Firefox下载插件的源码。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1495837|下面是我使用的Download+Statusbar的源代码。|offset|length|1495838|entityMap|0|LINK|mutability|MUTABLE|url|http://www.mozdev.org/source/browse/downloadstatusbar/^0|0|7|I|0|0^^$0|@$1|2|3|4|5|6|7|N|8|@]|9|@]|A|$]]|$1|B|3|C|5|6|7|O|8|@]|9|@$D|P|E|Q|1|R]]|A|$]]|$1|F|3|-4|5|6|7|S|8|@]|9|@]|A|$]]]|G|$H|$5|I|J|K|A|$L|M]]]]

Dont know, but you could perhaps check the source of one of the Firefox download addons.

Here is the source for one that I use <a href="http://www.mozdev.org/source/browse/downloadstatusbar/" rel="nofollow noreferrer">Download Statusbar</a>.

blocks|key|1281367|text|而不是像这样触发本机文件下载对话框：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1281368|By+DOWNLOAD_ANCHOR+=+By.partialLinkText("download");
driver.findElement(DOWNLOAD_ANCHOR).click();|code-block|syntax|javascript|1281369|我通常会这样做，以绕过本机的文件下载对话框。这样，它就可以在所有浏览器上运行：|1281370|String+downloadURL+=+driver.findElement(DOWNLOAD_ANCHOR).getAttribute("href");

Instead of triggering the native file-download dialog like so:

<pre><code>By DOWNLOAD_ANCHOR = By.partialLinkText("download");
driver.findElement(DOWNLOAD_ANCHOR).click();
</code></pre>

I usually do this instead, to bypass the native File Download dialog. This way it works on ALL browsers:

<pre><code>String downloadURL = driver.findElement(DOWNLOAD_ANCHOR).getAttribute("href");
File downloadedFile = getFileFromURL(downloadURL);
</code></pre>

This just requires that you implement method <code>getFileFromURL</code> that uses Apache HttpClient to download a file and return a File reference to you.

Similarly, if you happen to be using <a href="http://selenide.org/javadoc/3.3/com/codeborne/selenide/commands/DownloadFile.html" rel="nofollow noreferrer">Selenide</a>, it works the same way using the built-in <code>download()</code> function for handling file downloads.

blocks|key|1281152|text|我没有违背你的目标，你是否希望你的测试在测试执行时自动下载文件，如果是，那么你需要在测试执行中使用自定义的Firefox配置文件。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1281153|在自定义配置文件中，第一次手动执行测试，如果出现下载对话框，set+it+Save+it+to+Disk，Always+perform+this+action复选框将确保您下次运行测试时自动下载该文件。|1281154|entityMap^0|0|0^^$0|@$1|2|3|4|5|6|7|F|8|@]|9|@]|A|$]]|$1|B|3|C|5|6|7|G|8|@]|9|@]|A|$]]|$1|D|3|-4|5|6|7|H|8|@]|9|@]|A|$]]]|E|$]]

I didnt unserstood your objective, 
Do you wanted your test to automatically download file when test is getting executed, if yes, then You need to use custom Firefox profile in your test execution.

In the custom profile, for first time execute test manually and if download dialog comes, the set it Save it to Disk, also check Always perform this action checkbox which will ensure that file automatically get downloaded next time you run your test.

In addition you can add

<pre><code> profile.setPreference("browser.download.panel.shown",false);

To remove the downloaded file list that gets shown by default and covers up part of the web page.

<pre><code> DesiredCapabilities dc = DesiredCapabilities.firefox();
 dc.merge(capabillities);

Is there any kind of API that can allow me to manipulate a file download dialog in Firefox?
(I want to access the one that appears when user does something, not initiate one myself).

What I want to do is to access this dialog from Selenium (and whether Selenium "privileged mode" is enough to access chrome interface is something I am not sure about as well).

Access to file download dialog in Firefox

有没有什么API可以让我在Firefox中操作文件下载对话框？(我想访问用户执行某些操作时出现的消息，而不是我自己发起的消息)。我想要做的是从Selenium访问这个对话框( Selenium的“特权模式”是否足以访问chrome界面也是我不确定的事情)。
