12.19Firefox 3 Beta 2
The IE dev team has reported that Internet Explorer 8 will pass the Acid 2 test. Acid 2 tests a browser to see if it passes W3C web standards . Currently Opera and Safari pass Acid 2 and Firefox 3 will pass Acid 2. This will be great news to all web designers and will hopefully end hacks for IE to make websites work correctly.
