Internet Explorer 8 Test Result:

Firefox 3 Test Result:

Opera 9.5 Test Result:

As you can see - IE8 fails miserably! It initially only gets 10/100, but after a few seconds it increases to 17/100, which I find odd. Though admittedly IE8 is intended for developers to begin getting their pages compatible with IE8. Opera 9.5 also fails the test, though with a more respectable 60/100, which increased from somewhere around 47 after about a second or so.

Finally, Firefox 3, which scores 67/100 is the only browser I tested which doesn't have the word "fail" on the end result, though I don't think that counts as a pass because it didn't score 100.

For what it's worth, the end result should look like this reference rendering (as provided by acidtests.org).
