Let's continue here: [/questions/1064642] ------ Okay, I post the same question with a screenshot. When I click + to open a new tab,that tab only shows the address bar, no search box! This problem creates suddenly. Before, this problem, when I opened a new tab it shows address bar and google search box. Now, the address bar of new tab page worked as both search box and address bar. I have followed about:config process and it's worked. But, when I start my computer after few hours again I see that problem! What can I do? Please tell me. I have attached an image for your understanding.
