How to install and use javascript bookmarklets in Google Chrome, Safari or any other browser

Bookmarklets are small JavaScript programs that can be stored as bookmarks in a web browser. Unlike regular bookmarks, which simply navigate to a specific webpage, bookmarklets perform actions on the current page you are viewing. They are executed by clicking on the bookmark, triggering the JavaScript code embedded within.

Adding bookmarklet

There are several ways you can add a bookmarklet to your browser.

• Click and drag the link with js bookmarklet to your bookmark panel in the browser. For example, test this link (drag and drop it on your bookmarks panel) — Show page title.
• Just add new bookmark and in the address field add js code.
• Edit your any old bookmark. Copy js code and add it as the address of bookmark.
