Guys - minor warning - agree to disagree maybe. Different Browsers suit different people, Opera is good, so is Firefox, good and bad points all around. But please this has been a great thread lets not ruin it by it ending up in a slagging match.
I am sure its made a few Firefox converts and Opera converts in its time, and if we can keep it going maybe a few more.
So tell us the links for added extra, hints and tips, but remember not everyone is going to agree with you
