auto_favicon_gen is a free Chrome add-on developed by kaibadash. It falls under the category of Browsers and the subcategory of Add-ons & Tools. This add-on aims to solve the problem of finding websites with no favicons set when the tab bar becomes narrow and only displays the favicon.

In the tabbed browser of Chrome, it is common to have multiple tabs open. However, when the tab bar becomes too narrow, it becomes difficult to identify websites that do not have favicons. This extension addresses this issue by generating favicons from the website's title. This allows users to easily locate and identify websites even when the favicon is not available.

With auto_favicon_gen, users can navigate through their open tabs with ease, without the frustration of searching for websites without a favicon. This add-on provides a simple and effective solution to enhance the browsing experience in Chrome.
