Have installed Firefox on all three of my computers - PowerBook and Dell laptops, and my office PC - but I'm not sure yet if I want to permanently switch from Explorer/Safari. It's fast and stable, but I have a few issues. First off, it doesn't remember all of my passwords (there may be an easy fix to that, but I haven't found it); secondly, the backspace key doesn't work as a 'back one page' shortcut. I'm used to that from the other browsers, and it's hard to adjust. Yeah, I know about the security issues, but I've never had any real trouble with Explorer, and I like Safari a lot. I'll keep using Firefox in the weeks to come, so we'll see. I might adjust to it. Besides, change is good. I like change.
