hello there Need help about safari browser !

Hello anyone there:

I need help with the safari browser. I have been using this browser on my iPhone for the last two years, but now it is not working perfectly. According to my previous experience, I love to use safari now. When it wants to access some websites, it shows some warnings. Can you please check it? For example, when I want to access it always shows security warnings and suddenly disappears. any one, please help me about this problem
