Ooh, some one else has discovered the Acid Test! I don't have time to go through it, how close is firefox now? Last I saw, it was high 90s, but that wasn't the default settings, and was a few versions ago. Safari I know aced it, and a few others.
My top browsers:
1. Firefox
2. Chrome
3. Safari
That's all I use really, though I do have Opera and IE installed just for web design purposes (someone has to do the dirty testing...).
Really though, I can assure you from a web designer's viewpoint, IE is horrid. At first look to the untrained eye, it appears ok, but if you know it well enough, you will know not to use it. Your problem, Cat, is the same as grandmas. They simply don't know whats so bad about it because Microsoft hides it under the tables. Trust me when I say it is bad. Very bad.
