I cannot login to any Google.com site with Firefox. IE and Opera work fine. I cannot login to my Google account usning Firefox either.
Yesterday my Firefox started acting weird. I logged into my online banking and did an online money transfer no problem. Then about a half hour later I tried again and could not get to the banking site. It gives an error:
Unable to connect
Firefox can’t establish a connection to the server at [whatever].
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.
This also happens with Google when I try to go to Gmail, or to log in to my Google account, or access anything at Google.com. Google.CA works fine. All above websites work fine with IE and Opera. Most other sites also work properly with Firefox, just Google.com sites and my online banking refuse to connect. At least that's all I found so far.
Tried the standard clear cache, cookies, etc with no change. Looked at the Windows firewall, deleted Firefox and reinstated it in firewall, no effect. I have tried several of the suggestions in your knowledge base and none have made any difference.
HELP!!!

There is security software like Avast, Kaspersky, BitDefender and ESET that intercept secure connections and send their own certificate.

This Connection is Untrusted is sometimes caused because the computer system clock is wrong. Check the time / date / time zone settings.
I have tried disabling all my AV software except perhaps Microsoft.
Didn't help.
I do not get an untrusted site warning...
If it was AV software, would it not affect all browsers?
Got it. It was Trusteer protection for my browser.
Thanks.

Problem solved. Trusteer Endpoint Protection by IBM was the cause.
