About this extension
"Do you often find the text in YouTube Live Chat too small or hard to read? With YouTube Chat Resizer Pro, you can adjust this in an instant! Click on the extension icon in the top right, enter your desired font size (in pixels), press Enter, and the chat will be enlarged immediately. You don't need to refresh the page.
The extension is super fast, lightweight, and automatically remembers your preference for the next time you start a livestream. Ideal for watching streams on a larger screen, a TV, or a device like the Steam Deck!"
