Force Single Line for YouTube Live Chat is a Chrome extension developed by Simple and Tiny Utilities. This free tool falls under the Browsers category, specifically Add-ons & Tools. Its primary function is to condense YouTube live chat messages into one line each, preventing lengthy messages from occupying excessive space in the chat window.

With this extension, users can ensure that each message in the live chat appears on a single line, maintaining a clean and organized chat interface. By simply hovering over a message, users can still view the full content of the message without any truncation or loss of information.
