When I go to Tools-Options-General and make google.com my homepage and use current page (I have already gone to google.com from google.ca) and close Firefox and reopen it, the page has reverted to google.ca. I tried making Firefox the default browser, thinking this might be the problem, but it doesn't fix it. I am at a loss because, as you know changing your homepage is usually routine. I have run scans to see if there was a trojan or other lurking around, even though it seemed unlikely, but have found nothing. Would appreciate your help. Thanks, Bert.
