Is there a simple way of blocking or hiding referrers in windows home edition XP?
I think it will only possible into firewall settings.
Outpost Professional has this feature.
I suppose other firewall have it too.
Anyway, a lot of referrers are legit and you won’t able to browse freely blocking them.
It’s very easy to block/control sending referrers if you’re using Mozilla Suite/Mozilla Firefox. Some discussion of that over at Mozillazine: Link.
Whether you run into problems depends entirely on the sites you visit. I don’t send them, and generally have no problems.
You could also look into proxy software, such as Proxomitron. I believe filters are available to fake referrers.
