Try accessing the site using the secure URL, https://addons.mozilla.org . Let me know if this works.

If that address has the same error message, try https://63.245.217.40 . This last URL should give you a "Secure Connection Failed" error message. If it gives you this error, that means the test succeeded.

Reply back here with the results.

The result I received from using the first url was:

"The connection was reset. The connection to the server was reset while the page was loading."

The result I received using the second url the page loading, but without any formatting or background, it just didn't load correctly. When I refreshed the url to see if that would correct the page I received the same error message listed above.

The problem seems to be that traffic on your computer (or network) is being blocked. If this is a corporate computer, addons.mozilla.org may be blocked to enforce a policy that browser add-ons aren't used. If this is a personal computer, you may have your firewall or security settings set to block add-ons.

Interesting theory. It is a company computer, however, I used another employee's computer the other day, and none of the issues I described earlier occurred when using Firefox. But, still, it is something to consider.

I'm wondering if it is a java issue.
