## Description

**Javascript Control** is a handy Chrome extension that adds a toggle button to the URL bar, letting you block or enable Javascript on a per-site basis. By default, Javascript is disabled to improve your browsing security and control over web content. With a simple click, you can enable Javascript for trusted sites without navigating through complex settings.

While the extension supports Chrome fully, users should note that on Firefox for Android, some icon functionalities are limited due to platform restrictions; however, the core Javascript blocking feature remains effective. This extension is ideal for users looking for fine-grained control over Javascript execution to boost privacy and security while browsing.
