Not too long ago, I was browsing through my emails using Firefox (the version is 18.0.1). I am on an imac computer with the Snow Leopard operating system, and I have all the latest updates from Apple in Software Update.
I received an email from someone I know (through a game) and opened it. In the past, I have received emails from this person without any issues. When I opened up this email, there was just a link. Thinking it was safe as I knew the person (at least enough to open emails from them), I clicked on the link and it redirected me to another website. Immediately upon loading the website, I got a warning message that said this could be a fraud website. It all happened so fast because I wanted to get off of there, so please forgive me if I can't quote the message completely. There were two options below the message. I can't remember the one on the right, but the one on the left said something along the lines of "Get me off or out of here!" When I saw that, I clicked on it and it redirected me back to the Firefox homepage.
I then re-logged into my email account, deleted the emails, and then logged out. It all happened so fast, I didn't think to save the link to the website.
My questions are these: Since I was using Firefox, how safe was I? Even if I didn't enter any information on that website, can I be infected just by clicking on that link? Since I am on an imac, should I be safe?
Is there anything else I should do?
I have never experienced this before, so I am sort of worried.
I checked my Security Preferences for Phishing and Malware Protection, and they both were checked. Also, I went to Mozilla's phishing and malware test sites and they both were successfully blocked. The page I was referring to in my first post looked just like the phishing and malware test sites...which one I am not sure.
