What is a Bookmarklet?
A bookmarklet is a bookmark of a JavaScript code instead of a webpage, which acts as a quick button to perform a certain action.
Bookmarklet = Bookmark + Applet
Instead of taking the user to a certain URL, these bookmarklets trigger certain scripts and act as a micro-app or browser extension. They are also known as Favlets, Bookmark Applets, or JavaScript Bookmarks. They are lightweight and are supported by all major browsers.
For example, the following code: javascript:window.open(window.location.href) can open the current tab in a new tab.
We can bookmark this code to perform the function through a single click.
Just go to Bookmarks > Bookmark Manager > Add New Bookmark, add the bookmark name, and simply paste the JavaScript in the URL field.
Or you can also drag the links (provided below) to the bookmarks bar and create bookmarklets.
