Marionette-WARN-TLS certificate errors will be ignored for this session warning using GeckoDriver and Firefox through Selenium and Java

Question

Iam a beginner in Selenium WebDriver. I wrote a code to just navigate to a URL and login to that. Also to show a message in console of the string URL is correct as the current URL. The code is executing succesfully and is working as expected. Its logging in. But at the same time getting some warning messaged in the console. can some one please let me know the reason for the warning message? Is it because any jar files are missing? I'm using the latest versions of JDK and Selenium WebDriver. Please see below the code snippet and the console Error.

Code as below :

    package testSelenium1;  
    import org.openqa.selenium.By;
    import org.openqa.selenium.WebDriver;      
    import org.openqa.selenium.firefox.FirefoxDriver;
    public class admin {
    public static void main(String args[]) {  
 System.setProperty("webdriver.gecko.driver","C:\\Users\\30211170\\Downloads\\geckodriver-v0.26.0-win64\\geckodriver.exe");
    WebDriver driver = new FirefoxDriver();// Launches firefox browser with blank URL
    driver.get("http://www.gcrit.com/build3/admin/login.php?");
    driver.findElement(By.name("username")).sendKeys("admin"); 
    driver.findElement(By.name("password")).sendKeys("admin@123");
    driver.findElement(By.id("tdb1")).click();
 String url = driver.getCurrentUrl();
 if (url.equals("http://www.gcrit.com/build3/admin/index.php")) {
 System.out.println("Login is success");
 } else {
 System.out.println("Log in failed");
 } 
 }
}

Warning message as below :

It's some warnings. The only thing that's really interesting is the TLS warning, and my guess is that it's so that Selenium can proceed with testing in a self-signed environment. If your test worked, don't worry about it. — chrylis -cautiouslyoptimistic-, Dec 20 '19 at 08:23
@jayasrees Which `WARN` message are you concerned with _...WARN TLS certificate errors will be ignored for this session..._ ? — undetected Selenium, Dec 20 '19 at 09:40
@DebanjanB Yes. Also in Line 2,3,4,5 and some javascript error in line 6. I'm all new to this. So I don't know what these all mean. I can see 'WARN' in most of the lines which I assume as a warning message. — Sru, Dec 20 '19 at 12:51
@jayasrees Can you reduce the scope of your question to limit it to a specific problem to identify an adequate answer. Please avoid asking multiple distinct questions at once. — undetected Selenium, Dec 20 '19 at 12:55
@DebanjanB Sorry. Question is on the warning comments that I have attached under 'Warning message as below :'. Will those warnings be always there? I'm getting the expected result so do I need to take care of warnings? — Sru, Dec 20 '19 at 15:10
@jayasrees Those `WARNINGS` are from _Mozilla_ `addons` and are also unharmful. You are still safe :) — undetected Selenium, Dec 20 '19 at 15:12
