Many of our customers (that includes most of our engineers) use Firefox as our main web browser. There are some sites that just run better in Microsofts Internet Explorer (IE) and some that just don’t run at all without it. I just spotted a plug in for IE that lets you run IE as a tab within FireFox.
Get hold of ietab here. Great stuff and it works perfectly too.
Pitty there’s no OS X version but it makes sense I suppose
