I want to execute my Selenium tests in different languages. Is it possible to change the language of an existing WebDriver at runtime or do I have to recreate the browser instance?

Right now I'm only using Firefox, but I want to execute tests in different browsers at some later point.

In Firefox I set the language like this:

FirefoxProfile profile = new FirefoxProfile();
profile.setPreference("intl.accept_languages", "de");
WebDriver driver = new FirefoxDriver(profile);

I also implemented a WebDriverPool, which holds a WebDriver instance so it can be shared among tests. If the language can only be set at creation time, I could hold an instance for every locale.

All in all I wonder if I miss something here. Why is it so hard to change the language? shouldn't there be a method like WebDriver.setAcceptLanguages(Locale)?

In a nutshell I have these questions:

  1. Why isn't there WebDriver.setAcceptLanguages(Locale)?
  2. How to change the language for the dirrerent WebDrivers?
  3. Can I change the language at runtime?
  4. How did you guys implement your WebDriverPool or do you recreate them everytime?
