Vista and Mozilla - Testing my Patience

Curses! That's the most I can say when it comes to mouthing a bad word. Curses! I can think of all the curses known to man right now because of this issue with Vista OR Mozilla 3. I re-installed the updated version of Mozilla so I can open Yahoo properly. Lo and behold, I still cannot connect properly. I have to restart, reboot the router, clear the cache and cookies, disable some stuff and yet, I still cannot open the usual websites I frequent to using the older version of Mozilla.

This thing is really wearing my patience thin. I swear I could throw my laptop any moment now. I feel a little frustrated because I am not an IT expert so I don't understand what's happening, if it's Vista at fault, my browser, my firewall, my security settings...what?

I decided to downgrade my Mozilla to version 2 just so I can open the sites again and I managed to do that. It's starting to shed light now, I have a funny feeling that Vista has something to do with all this hullabaloos!

I need more patience! And I need it pronto!!!

What's Wrong with Vista?

Can someone please tell me if Vista is a good operating system than the XP? Honestly, I thought it was initially when I bought my laptop last year as it was installed with Vista instead of the XP but as I progress with my usage of the OS (operating system), I find so many quirky things like it hangs, I cannot visit some site (most likely because I have a very tight firewall?!?) which I used to open using XP and now that I have updated my Mozilla, I cannot open Yahoo, I cannot connect but I have my connection all working properly. As a matter of fact, I am using my bro's laptop right now which is also connected in my network at home. Is it Yahoo, is it Mozilla or is it Vista? What's wrong???? So, I don't think I'll be able to post my Milan and Rome pics soon as I figure out what to do. Who are the experts here? Please help!!!!!!!! Do I need to downgrade my Mozilla again to ver 2? I noticed that when I upgraded yesterday to ver 3, I cannot open any sites. Grrrrrrrrrrr. This is just like severing my 2nd lifeline!

Ciao!
