By no means am I going to stand here and tell you because Firefox did lousy and IE7 straight up failed this instance of a recent Acid3 test, that you should immediately stop using those browsers and jump onto the Opera bandwagon. That would be stupid. Why? Because to this day, there are relatively important websites that will not work with Opera, barely work with Firefox and despite the fact that we no longer live in the 90’s, require IE as it is “easier” for the admins of these culprit websites.
That being said, unfortunately the problem is more of an issue with marketshare over what is actually making up a good browser. Internet Explorer is not and has never been a good standards friendly browser. It has market share, so all of the Frontpage designed crap out there is sure to look great through the browser’s beer goggles. Should we keep an open mind about Opera 10 despite this? Sure, assuming the same old problems do not keep cropping up again and again with regard to how a website looks or reacts to an otherwise good Opera browser option.
