Invalid security certificate

[TimeParadoX]

I reinstalled FireFox today, and when I try to go to websites that are offical (Mozilla, Blizzard, etc) it'll say it has a expired seucirty certificate.

addons.mozilla.org uses an invalid security certificate.

The certificate will not be valid until 9/19/2008 12:09 PM.

(Error code: sec_error_expired_certificate)

* This could be a problem with the server's configuration, or it could be someone trying to impersonate the server.

* If you have connected to this server successfully in the past, the error may be temporary, and you can try again later.

It appears like that for the addons part of Mozilla.org.

Is there a way to fix this, or is it just a problem with the new version of FireFox?

Bump, Also, Avast! has been having a problem with updating.

"- your system time/date has changed; fix it and enter the license key again", is there a way to fix this? I didn't change my time/date on my system.

Okay, nevermind. I just found out what I did, I set the date/time on my computer 10 years ahead to exploit a game (You get money every day, so 10 years ahead will get a lot of money. ) and I realized this during a reformat... So... This thread could be deleted now.
