Different test behavior in Chrome and Firefox [duplicate]

I have task - write test for the page https://cloud.google.com/products/calculator

In the Chrome test work without problem. In the Firefox I get Exception NoSuchFrame.

driver.switchTo().frame(0);
driver.switchTo().frame("myFrame");
Webelement numberOfInstances = new WebDriverWait(driver, 15)
                .until(ExpectedConditions.visibilityOf(element));
numberOfInstances.sendKeys("4");

After I correct code on that

driver.switchTo().frame(0);
new WebDriverWait(driver, 10)
       .until(ExpectedConditions.frameToBeAvailableAndSwitchToIt("myFrame"));
Webelement numberOfInstances = new WebDriverWait(driver, 15)
       .until(ExpectedConditions.visibilityOf(element));
numberOfInstances.sendKeys("4");

And now I get other exception: TypeError: can't access dead object
