Could you explain this in a bit more detail. Are you getting an error message from Google or other sites? Or from Firefox when you try to access those sites? If so, what is the error message?

If you have problems with the secure certificates for all secure sites, one common cause is a system clock that is set for a different date or time. This might affect other browsers as well.

Which problems did you have that you decided to reset Firefox?

Note that if you have visited pages before on a server via a secure connection then Firefox will prefer to using a secure connection (a reset imports the history).

You can set the Boolean browser.urlbar.autoFill pref to false to disable auto-fill on the location bar.
