I cannot upload files with selenium web driver.

[rleaplaza]

I have a problem uploading a file via selenium web driver v.3.5.3 in firefox 55.0.3
Geckodriver 0.18.0
Both of the instructions are correct.:
WebElement elem=driver.findElement(By.xpath("//input[@type='file']"));
elem.sendKeys("C:\opt\formatos_excel_importacion\prueba.txt");
In Google chrome it works fine, but it doesn't do the same in firefox.

The error says: Exception in thread "main" org.openqa.selenium.InvalidArgumentException: File not found: C:\opt\formatos_excel_importacion\prueba.txt

Thanks for the advices, I found the solution to my problem.
FirefoxProfile profile=new FirefoxProfile();
profile.setPreference("dom.file.createInChild",true);
DesiredCapabilities capabilities=DesiredCapabilities.firefox();
capabilities.setCapability(FirefoxDriver.PROFILE,profile);
driver=new FirefoxDriver(capabilities);
Now I can upload files normally.
I know the problem will be solved for the next Firefox version.
