This welcome page might also provide some advice, as shown above, about "invalid security certificate" warnings and the need to accept them in order to use Psiphon. In fact, these instructions are outdated, and you should no longer follow them. If, when connecting to a Psiphon proxy, you see warnings such as those displayed below, you should pay attention to them. If that happens, you might want to close your browser and contact [email protected] or [email protected] for additional advice.
