Mibbit Mibbit Mibbit is a web-based client for web browsers that supports Internet Relay Chat (IRC), Yahoo! Messenger, and Twitter. It is developed by Jimmy Moore and is designed around the Ajax model with a user interface written in JavaScript. It is the IRC application setup by default on Firefox. Mibbit's user interface operates entirely within a web browser and does not require installation of any software on the user's computer. Most modern web browsers that support recent versions of JavaScript are supported, including Mozilla Firefox, Internet Explorer, Opera, Google Chrome, and Safari.

Google Chrome results in a "Sad Tab" screen of death, similar to the well-known "Sad Mac", but only one tab crashes instead of the whole application. This strategy exacts a fixed per-process cost up front, but results in less memory bloat over time as fragmentation is confined to each instance and no longer needs further memory allocations. This architecture was adopted in Safari and Firefox. Chrome includes a process management utility called "Task Manager" which lets users see what sites and plugins are using the most memory, downloading the most bytes and overusing the CPU and provides the ability to terminate them.
