You appear to be using Firefox 3.6.23, which is the earliest secure and supported version of firefox. You may not have up to date plugins, use http://www.mozilla.org/en-US/plugincheck/ to check and update your plugins.

It can not be recommended that you try any earlier unsupported and insecure versions of firefox, that would put your computer and the personal data it contains at risk.

After you have updated post back, if you have problems with a publicly accessible site pleas provide a link, and explain what the problem is. (It is probably worth checking any forums or faqs relating to problematic sites)

I updated the flashdrive and silverlight. I still can't get to a game on pogo.com. It loads so far and never finishes. Also, it almost completely loads and never finishes. Gmail and other sites are doing this too.

Sorry I am unable to help, I do use gmail but am not a Mac user. There will be many users who use gmail, what is the problem exactly with that?

(I will be able to test that on Firefox 3.6.23, but only on a Windows XP, it would be better if a Mac user is able to assist you)
