Select the “back” button of the Firefox browser to right click and Select the Option from the right click Menu in Selenium Web Driver - Java

Hello All, 

I am using Selenium Webdriver . I want to select the "back " button of the firefox browser and right click the back button and select an option.

I see there is "Actions" API to right click, But i am not able to select/find the "back" button element of the firefox  browserto right click using selenium .

Can any one please help me .

Code iam trying is :: Using firefox Driver to inittate the Webdriver

Actions action= new Actions(driver);
    action.contextClick(productLink).sendKeys(Keys.ARROW_DOWN).sendKeys(Keys.ARROW_DOWN).sendKeys(Keys.RETURN).build().perform();
    
    
    In the above code , in place of "productlink", i should select the back button element of the firefox browser to right click .

Thanks,
Deepthi
