MOHA Chat is a chat solution which comes with a intuitive Web client and can run on most shared hosts. MOHA Chat consumes fewer resources on the server side and is fast on the client side. It uses AJAX to retrieve the chat messages and user status. The client polls the server at regular intervals. It currently supports only one-to-one chatting with the Web client. The Web client encrypts messages using a key unique to the client when sending a message to the server and vice versa.
Pactester is a tool to test proxy auto-configuration (PAC) files. PAC files are used by browsers to identify the correct proxy server for a given URL. Since the PAC file evaluation mechanism is generated inside the browser and cannot be accessed from outside, the only way to tell which proxy your browser will use for a specific URL is manual inspection of the PAC file. Unfortunately, this approach is error prone and quickly becomes impractical for large and complex PAC files. Pactester resolves this issue by simulating browser behavior.
Firekeeper is an intrusion detection and prevention system for Firefox. It is able to detect, block and warn the user about malicious sites. Firekeeper uses flexible rules similar to Snort ones to describe browser-based attack attempts. Rules can also be used to effectively filter different kinds of unwanted content.
