Firefox and other browsers can't load websites
If you're having the same problems loading websites on every browser, these are some possible causes and ways to fix them.

Security software is blocking the connection
Check if your Internet security software (including firewalls, antivirus programs, anti-spyware programs, and more) is blocking the connection to the Internet. For instructions on how to configure some programs, read Configure firewalls so that Firefox can access the Internet.
System time is incorrect
Your system's date, time and timezone settings are configured correctly. Firefox may have issues validating the website's security certificate if the date/time is incorrect.
If you are using a wireless connection, make sure that you are using the correct access point.
Internet Service Provider problem
Even if your modem and/or router are both on and are not indicating errors, the problem may be with your Internet Service Provider (ISP). Contact your ISP for more information.
Your Domain Name System (DNS) server translates web addresses (URLs) into IP addresses and is usually provided by your ISP. If the DNS server is overloaded, you may be unable to view some or all websites. For example, if http://184.108.40.206 or http://220.127.116.11 work but http://www.google.com doesn't, you may have a DNS problem. You can use an alternative service such as OpenDNS or Google Public DNS.
If neither Firefox nor your other browser can load any websites, your problem is external to Firefox and you should seek support elsewhere.
