The categories on the right hand side were dropping down the page in firefox 3, so I’ve simplified the CSS for these and it now works in Firefox 3 and Internet Explorer. Previously it never worked in Internet Explorer properly so it was a bonus when I got it working in firefox to see it right in IE!
I’m going to presume the change works in all other browsers until I know any different!
So – I found an issue with firefox3 – the div for the categories was covering the top post on the page so you couldn’t click any links to go anywhere – I believe I’ve resolved this and it still appears to work fine in IE7 and Firefox 3.
