Regardless of the type of browser and ease of use, its performance can always be improved by installing extensions that improve performance, increase security and even serve as entertainment. Such (and more) extensions will be discussed later in the article, which aims to familiarize you with the most popular extensions of various browsers, which will be useful for both beginner testers and experienced QA gurus.
Useful browser extensions for a tester
What are browser extensions and what are they used for?
A browser extension is a program that aims to supplement or improve its functionality. The main purpose of installing add-ons is «to extend» the functionality of the browser. Instead of going to special sites each time to check the spelling of a word, you can install an extension that will correct and prompt you as you type. With extensions, you can embed items in cloud storage and, for example, create your own microservice. Extensions can also be called add-ons and plug-ins.
Extensions can not only improve the testing process, but also be an obstacle to it.
There are extensions that can load the PC's RAM, thereby slowing down the speed of the browser used. There are also many virus extensions, the installation of which runs the risk of harming the operating system. Often, such applications can track a user's search history or use their personal data without their permission (it is difficult to imagine what this could lead to on a desktop computer where logins, passwords, cookies and other sensitive information are stored). Therefore, you must first install extensions from verified and licensed sources.
