# How to enable press tab to search in Google Chrome and Mozilla Firefox on your website Today, I learned something new while using StackOverflow in google chrome that it provides special area in browser's address bar to search on the site even before you visit the site. I think this is very good feature as user can find the things very quickly on your site and get the expected output as soon as possible without having to see unnecessary details. In image below you can see that I have enabled it for this site, it is visible in browser's address bar and just below it you can compare it with the StackOverflow's search in address bar.
