Where are the places you changed Canadian English to U.S. English?

The setting on the MSN website probably is specific to MSN or maybe Microsoft site, probably stored in a cookie, and isn't picked up by Firefox itself as a global setting.

Was there a setting you changed in Firefox, for example, on the Options page or in about:config? I suspect Firefox actually doesn't know Canadian English from U.S. or U.K. English and there may not be any way to stop websites from using geolocation to guess your preferred language.

Such detail is likely stored in a cookie.

You can use these steps to make a website recognize and remember you:

• Create a cookie 'allow' exception to keep such cookies, especially in case of secure websites and when cookies expire when Firefox is closed.
• Tools > Options > Privacy > "Use custom settings for history" > Cookies: Exceptions

If you remove such a cookie then the website will forget your choice and you will have to repeat this.

I deleted all cookies, reinstalled Mozilla and made MSN my homepage once again....thinking it may be an MSN cookie related issue as suggested. However, once again, when I selected MSN as my homepage, it once again reverted to the Canadian site. This did NOT occur in either Chrome or IE and was unique to Firefox. However....when I went into Firefox settings and forced Firefox to revert to "restore to default" homepage in the general settings tab in Firefox...it went (obviously to Mozilla). Then when I went back to the same tab and MANUALLY entered the MSN US homepage link....tada!!!! No more Canadian English homepage. Strange....eh? :-)

I then restored all my old cookies and it remains on the US MSN homepage.

Thanks for all your help and hope this helps someone else!

Did you previous use a bookmark?
