Getting Popup when click on save button even no changes done in form

Hi ,

i am getting popup message when i clicked on save button when even i am normally saving data in form in 3 modules : lead , account and contact.

Popup Msg details is : “This page is asking you to confirm that you want to leave - data you have entered may not be saved” with buttons:
1. Leave page
2. Stay on page
even i clicked on “leave on page data saved sucessfully”.

i want to remove this pop up is there any way can anyone suggest me to solve this problem??
