Unchecker is a Firefox extension designed to enhance user privacy by simplifying the process of managing checkboxes on websites. With the GDPR regulations in mind, many websites require users to manually untick numerous boxes to opt-out of data collection, which can be cumbersome. This extension allows users to easily check or uncheck all checkboxes simultaneously, saving time and effort while ensuring better control over personal data.

In addition to its primary functionality, Unchecker offers a convenient feature to address websites that utilize buttons instead of checkboxes. The 'Click all similar buttons' option enables users to click on all buttons with the same label in one action, effectively disabling unwanted options. This user-friendly tool streamlines the process of maintaining privacy online, making it a valuable asset for Firefox users.
