I'm using an iMac (OSX 10.5.6 if that means anything to you - it doesn't to me!) I use Safari as my web browser; it came with the Mac, and I have no idea how it got there.
I'm trying to post an article on a writers' site, but the tech people there tell me that I have to be using Firefox (or Internet Explorer - but I can't use that on a Mac, can I?) rather than Safari, or else I can't post.
I've looked up Firefox on the internet, and it doesn't look much different from Safari. What I want to know is whether I will harm the way my Mac works if I just download Firefox. Will it replace Safari, or would I have to uninstall Safari first? And is Firefox any good?
I am very confused, and would welcome any advice!
