Question

It is not possible to get iFrame ID using firefox-firebug.

I want to get that iframe id i go to page source and manually search it from there.

for selenium automation under the controls of iframe

driver.switchTo().frame("");

Answer 1

If there’s a name or id on the iframe, Firebug should show it (at least in the DOM tab of the element – rightclick the element and select Inspect in DOM tab). If there’s no name or id, no tool will help you getting it.

You should consider selecting the frame via

driver.switchTo().frame(int index)

or (my favourite)

driver.switchTo().frame(WebElement frameElement)
