Modern browsers are equipped with all sorts of functionalities, i.e., from bookmarks to GPS location tracking, developer tools, and more. Almost all modern web browsers have immense capabilities – Firefox has built-in screenshot capabilities, Opera has a free VPN, and Edge comes with built-in support for displaying ebooks with the EPUB extension. Though browsers like Firefox, Chrome, and others are majorly used for web browsing, the fact is that Add Ons (or extensions) in Firefox provide additional power to the web browser! The same rule of thumb applies to other browsers like Chrome, Edge, etc.

Additional add-ons, plugins, and extensions are required to extend or customize browser functionalities, boost productivity, and suit the specific requirements of users and developers. Test automation engineers that use test automation can also benefit from browser extensions like normal end-users. In fact, testers often need to automate the testing of these extensions itself :slightly_smiling_face:
