# Why websites are not open by writing their "URL" in the address bar of any "web browser" in fedora23?

I am using firefox and seamonkey web browsers. often after connecting to the internet the web browsers are not able to open any websites not even GOOGLE by writing their url in the address bar. At the same time i am able to search everything with the default search engine of the web browser. I don't know why this happens so often. i am currently using fedora23. someone please help me to escape out from this.

So, what's the error message that the browsers are giving you? I am assuming you are not connected to the internet? try ping google.com from a terminal window next time your browser doesn't let you browse.
The ? means that you lost connection to the internet. Fedora regularly (don't remember the interval) pings fedoraproject.org, and if it can't reach the server it thinks that it lost internet connectivity. So, when you see this ?, what happens if you type ping google.com in a terminal? Are you sure this is not a problem with your router, modem, or provider?
