PC Problems...sigh

I'm not too happy with Opera at the moment. I've been using this browser for ages and I quite like the interface. Everything worked fine - until now! Even with the updated version the pages I call up don't load completely or stop loading entirely. Yesterday, Opera completely shut down by itself...
So, I'm using Mozilla now. I will need to import all my important bookmarked sites. I wonder if Mozilla has a feature that let's me call up my favourite sites quickly (like Opera does). Can anyone enlighten me on this?

Attention all Entrecarders: If I don't reciprocate drops, it's because I can't seem to log in to Entrecard! And when I finally do, the 'drop' doesn't work. Also had to approve an advert twice - hope that worked at least! Entrecard seems to be lagging! So...I apologize in advance.

I really hope someone will help me solve my PC problem...
