Firefox: Do Not Want ?

So, firefox has been behaving like a real Turd Ferguson lately, which makes me sad.
I started using firefox regularly (At home) about a year ago when I started using a Mac at work.
The only real problem I've had with it is it's frequent loading of 'nothing' pages. In other words, you click a bookmark or click a link and it takes you to a blank page. After that, you cant go anywhere without exiting the program and re-opening. Sometimes, even that doesn't work and you have to reboot the computer. Annoying as piss, but forgivable as it doesn't happen with every use. I'd peg it at about 25% of the time.
Well, yesterday Firefox decided to pull a new rabbit out of it's hat. Now, when I open it, all of my bookmarks, all of my plugins, skins, etc. are gone and it loads the whole "Welcome to Firefox, First Time User!!!!" welcome page bullshit. The first time it did that, and I though I'd lost all of my bookmarks, I was pissed. I learned where to recover them from a temporary backup thing that firefox creates daily, and thankfully that worked, but now I have to go through this process every time I start the fucking program. I've got the latest version, and I hadn't changed anything when this little gem of a problem flared up. Anyone got any ideas?
I certainly don't want to have to start using IE again, since its basically crap. Has anyone used Safari for PC? Does it work well?
I got my new camera this week. There is a ton of features and crap to try to learn on it, and I've barely started. I have pretty much just kept it on manual and been playing around with the aperture/ISO/shutter speed/focus settings so that I can get better at understanding what settings work best in what conditions.
Below are a few shots I've taken. They aren't anything 'thought out' in regards to composition, just seeing how the manual controls work and testing out the color correctness.
