Tampermonkey
Tampermonkey is a popular browser extension that allows users to install and manage user scripts, which are small pieces of JavaScript code that modify the behavior and appearance of web pages. It provides a user-friendly interface for managing scripts, enabling automatic updates, and controlling script execution on specific sites. This tool is widely used for customizing web experiences, automating tasks, and enhancing functionality on websites.
Developers should learn Tampermonkey when they need to customize or automate interactions with web pages without modifying the site's source code, such as for testing, scraping data, or adding features to third-party sites. It is particularly useful for creating quick prototypes, debugging, or improving productivity by automating repetitive web tasks, like form filling or content filtering.
