I get this error when using links to access my website jjmusic.co.uk. The page you are trying to view cannot be shown because it uses an invalid or unsupported form of compression. It works OK in Explorer and used to work in Firefox.

I can access the site direct but cannot access it from any of my links which have similar code:

<A href="http://www.jjmusic.co.uk">Return To Music Index</A>

Once this error occurs I have to clear the cache to access the site at all with Firefox, although explorer is OK. The fault occurs with other computers.

I can clear the cache and get back to my site OK, but other computers running XP also get this problem which means that a great many people can no longer access my site with Firefox. I need to resolve this issue possibly with a change to my link code (It's OK getting to the site via the address or returning with the back button), or a fix to Firefox'

Problem partially resolved by removing "refresh once" code, although this works OK on my other sites without problems and with other browsers.
