Selenium 2 WebDriver to use Custom Firefox Profile

[ytsejammer]

Hi,

I'm trying to automate the interaction with a website that generates
documents with MIME type application/vnd.wap.xhtml+xml. I am using
Selenium 2, the WebDriver and the FirefoxProfile.

Because Firefox does not handle the above mentioned MIME type, I need
to run Firefox with the XHTML Mobile Profile extension (https://
addons.mozilla.org/en-US/firefox/addon/1345/).

After creating a FireFox profile -I named it 'selenium'- and
installing the Mobile Profile extension to it, I tried to use the code
snippets in the 'Tips and Tricks' section of the 'Selenium 2.0 and
WebDriver' document (http://seleniumhq.org/docs/
09_webdriver.html#htmlunit-driver).

Approach #1 looks like this:

ProfilesIni allProfiles = new ProfilesIni();
FirefoxProfile profile = allProfiles.getProfile("selenium");
profile.setPreference("general.useragent.override", "User Agent string
to force application/vnd.wap.xhtml+xml content..");
FirefoxDriver driver = new FirefoxDriver(profile);
driver.get("http://www.mobilesite.com/");
WebElement element = driver.findElement(By.tagName("body"));


Approach #2 looks like this:

File profileDir = new File("/path/to/custom/profile/with/extension/
ffprofile");
FirefoxProfile profile = new FirefoxProfile(profileDir);
profile.setPreference("general.useragent.override", "same user agent
string as above");
FirefoxDriver driver = new FirefoxDriver(profile);
driver.get("http://www.mobilesite.com/");


No matter what code snippet I use, the browser instance that starts up
is always unable to handle the generated content; the browser prompts
me for an action to take on the content of the unrecognized MIME type
as if the extension was not correctly configured.

Any ideas on what I could be doing wrong?

Thanks in advance,
