Many people wonder why the same website looks different on a mobile device compared to a computer. This is mainly related to the browser's Kernel version. Websites use the Kernel information included in the request to determine the source device and browser, delivering a rendering that matches accordingly.

If the information your browser shares with a website (i.e., User-Agent) does not match the actual browser Kernel, it may cause a series of issues, affecting your online privacy, access to certain services, or data collection.

In this article, we will show you how to easily check your browser's Kernel version, hoping to be helpful.
