At Acumentum we always test our designs on multiple browsers. As we all know, one of the great pains in our business is getting a design to look, as it should, across a variety of browsers.
Internet Explorer 6 is still the most common browser on the web, yet in our office most people are running Firefox 2.0 and IE7. This makes quick testing, as you go, a pain, as IE5, IE5.5, IE6 and IE7 cannot co-exist on the same machine…or at least that used to be the case.
This is one of the most useful tools I’ve seen this year.
