I have used these sites 

-www.facebook.com

-www.dubbedonline.tv/ and some others for a long time but few weeks ago i couldn't access them anymore and this appeared : Unable to connect

Firefox can't establish a connection to the server at www.facebook.com. 

   The site could be temporarily unavailable or too busy. Try again in a few moments.
   If you are unable to load any pages, check your computer's network connection.
   If your computer or network is protected by a firewall or proxy, make sure that Firefox is permitted to access the Web.

i have also tried many ways to access them but none of the solution worked, one of them was checking troubleshooting problems and it detected that the remote device won't accept the connection, so, how can i fix this?

You can check the connection settings.

If you do not need to use a proxy to connect to internet then try to select "No Proxy" if "Use the system proxy settings" or one of the others do not work properly.

See "Firefox connection settings":

Do a malware check with several malware scanning programs on the Windows computer. Please scan with all programs because each program detects different malware. All these programs have free versions.

Make sure that you update each program to get the latest version of their databases before doing a scan.

You can also do a check for a rootkit infection with TDSSKiller.
