I use both chrome & firefox, but favor on chrome so totally didnt notice firefox have the .com.my problem after I fixed it on chrome.

so far, to stay on google.com using firefox , that would be everytime you open firefox browser, just use the " /nvr " trick, and dont close the browser,

it will stay at google.com as long as you didnt close the browser, (even if you close, just type the /ncr on the http link again, everything will be staying as "english", haha
