Do you see this proxy in the Firefox connection settings? You can check the connection settings. *Tools > Options > Advanced > Network : Connection > Settings *https://support.mozilla.org/kb/Options+window+-+Advanced+panel 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.

Thanks for replying I tried all 4 options under internet connections, Firefox would give me proxy error messages when I'd try to go on some websites. But now it's fine, I'm not sure what did it. I know a website was in another language, it was a redirect, but I was able to access the US version by clicking on a fix link, and now it doesn't redirect me. A website that helped was: [http://amibehindaproxy.com amibehindaproxy.com] It said I'm no longer behind a proxy, so I guess problem solved ?
