Stop Redirect Gmail Splash Page

Author(s):



From a few months ago, when I access https://mail.google.com/ to open a Gmail, sign-in screen of Gmail is that I should see if it normally would,
But It redirected to the Gmail splash page https://mail.google.com/intl/en/mail/help/about.html.
It will be redirected at the timing of something, not always be redirected to, But if it happens it remains to be redirected much after that.

Now I investigate this phenomenon. Redirect happens after Google search on https://www.google.com, and I found the cause of redirect, it was "NID" cookies of .google.com domain.

Steps to reproduce redirect phenomenon as below.
  1. Start Firefox
  2. Clear all cookies
  3. open https://mail.google.com/
    --> no redirect
  4. search "Firefox" on www.google.com
    --> added two cookies "PREF" and "NID" into .google.com domain.
  5. open https://mail.google.com/
    --> redirect to splash page https://mail.google.com/intl/en/mail/help/about.html
  6. remove NID cookie
  7. open https://mail.google.com/
    --> no redirect, Sign-in page come up.
Google Official document "Types of cookies used by Google" said "NID cookie is using for advertising".
So I create this addon for stop redirect by remove NID cookie automatically when you open Gmail top page.

Known Issues:
On high performance PC, sometimes prevent redirect to splash page was failed. Because Gmail redirect to splash page so quickly before prevent it.
I'm looking for a way to work correctly.
