Don’t feel alone. I don’t understand what that error message is saying either. I’m just plagued with it!
It’s a tech problem at work. It’s an incompatibility between Firefox 3.0, Google’s encrypted sites (like Gmail, Adsense, Webmaster Tools, Google Docs, etc) and our Fortigate firewall. Intermittently my web requests to Google get rejected with error messages. It can take a half dozen retries before my Gmail is sent or other task completed.
It’s a strange problem because it’s both software related and intermittent. You expect problems like these to follow hard and fast rules. What am I doing differently the fifth time I press retry than the fourth or third or second?
There is very little about this online. I can find people with my problem. I find a smaller subset who’ve realized it’s this specific firewall box that’s the wild card. I can’t find anyone with concrete tips to make the problem go away!
It wasn’t this way until Firefox went from version 2 to 3. It only happens with Google’s SSL encrypted sites.
It’s driving me slightly nuts.

Have you asked your IT guy to check the firewall log at the times you try to do this? There may be something getting logged.
It could be that the SSL traffic coming into the firewall is getting blocked even though the outbound request is opening port 443.
If you’re running Windows XP or heaven forbid Vista did you try disabling Windows firewall?

Comment above mine is correct, change the fortigate to allow unknown session ID’s.
This is only a problem because Firefox is more strict about following SSL rules than IE, and SSL3 does not allow resending sessionID’s for the fortigate to cache.
Reducing to SSL2 should work too if Firefox.
