Efficiency is vital when it comes to QA Testing. For testing websites and web applications, adding plug-ins like Chrome extensions can speed up the process for manual testers.

When testing on a desktop, there are multiple browser options to choose from (Chrome, Safari, Firefox, and Edge for example). It can be beneficial to test on all of these browsers. Testing on Google Chrome, though, has the advantage of multiple extensions QA testers can use to make web testing more efficient and accurate.

We’ve updated this list for 2021, so check out some of the top Chrome extensions for QA testers.
