The Endorser is a free Chrome extension developed by Tbunz. It falls under the category of Browsers and specifically the subcategory of Add-ons & Tools. This handy tool allows you to endorse all of your friends' skills on LinkedIn in a single click, making the process quick and efficient.

With the Endorser, you no longer have to endorse your friends' skills on LinkedIn one at a time. This extension has been updated to work seamlessly with the newest changes on LinkedIn, ensuring a smooth experience. Whether you want to endorse a friend or return the favor of a fellow endorser, the Endorser makes it easy.

In addition to its main feature, the Endorser offers a few other useful functionalities. You can de-select all previously endorsed skills if needed, allowing you to customize your endorsements. Furthermore, the extension provides the option to show or hide the styles applied to each element on the page, giving you more control over your LinkedIn experience.

Please note that the Endorser is only compatible when you are on a LinkedIn page. It simplifies the process of endorsing your friends' skills, making it a valuable tool for LinkedIn users.
