Hints, Tips & Know Issues

Capcha popups from Google

This has been an ongoing problem for some time. It only affects our traffic from IPV6 addresses.

As a workaround, ~djsd100/4google.xml is a search engine definition which, placed in ~/firefox/[profile name]/searchplugins will give you a "Google IPV4 search", which uses ipv4.google.com explicitly. (The profile name is usually 8 alphanumeric characters, a full stop, and the name presented to you in the Firefox Profile Manager).
