I don't think it's a browser issue or a "publishing" issue. Publishing is nothing more than the act of uploading your files to your web site. There is no such thing as a 30 minute publishing delay. However, the ".tk" and ".co.uk" "free" domain names are usually rather slow and not very reliable. I have tried them all before and haven't found them very useful. It can take a little time for changes to get through their systems.

Hey Martin, we do have computers on this side of the Atlantic. The only difference between .co.uk and .com is a couple of thousand miles of ocean with some high capacity telecoms cables underneath it.
