Safari blocks all UK websites? Suddenly no site in the UK will open in Safari (10.8.2 OS/6.0.2 Safari): BBC.co.uk, virgin.co.uk, apple.co.uk, amazon.co.uk, bobsyeruncle.co.uk, etc - every UK site is unavailable. Safari generates a "Failed to Open Page / Safari cannot connect to server" error. It's as if the entire range of servers in the UK have been denied.

Yet if I use Chrome or Firefox, no problem; UK sites pop open without issue, so it's likely not a system issue (etc/hosts). If I open a different user, Safari opens the UK site fine - the problem only seems to affect this one account. Unfortunately it's my work account.

What I've done (nothing has worked):


Checked proxies, none on
Uninstalled Safari Extentions
Removed Safari preferences
Fixed disk permissions
Flushed DNS caches
Removed Safari files from the ~/Library/Saved Application State folder
Removed Safari folder from ~/Library/


Okay - I give up. What have I missed?
It ended-up being even more simple: Little Snitch somehow blocked all domains within the UK range. I didn't know it could do that! I discovered it by rebooting in safe mode and discovering it did work, then removing anything running on boot.
