The s at the end is for secure.
If Firefox (I've got 3.0.14, might be different in other versions) go to Tools>Options>Encryption tab and see if option for SSL3.0 is checked (the first S is for secure also).
My job requires that I monitor a couple of websites at all times. I can log in to them just fine at work because they insist on using IE. I personally dislike IE, so when I work from home, I wanted to use Firefox or at least Safari. But there are a couple websites that won't open in FF or Safari. The only difference I am aware of is that they have an "s" after the "http". But I'm not sure if that's the only difference. I would really like to use FF or Safari rather than IE. Please advise. Thank you for any and all responses.
