Top 13 Chrome extensions for testers

StatCounter reports that 64.53% of users worldwide use Chrome as their primary browser. It’s not only the convenience of services and download speed that makes it so popular but also the fact that Chrome is one of the few browsers equipped with various extensions.

StatCounter reports that 64.53% of users worldwide use Chrome as their primary browser. It’s not only the convenience of services and download speed that makes it so popular but also the fact that Chrome is one of the few browsers equipped with various extensions.

Less switching between tabs, while you work, is a great advantage for developers and testers, which ultimately saves time.

Here are some key statistics from Pega’s research on how switching tabs significantly  affects the average IT team’s productivity:


People switch apps on average over 1,100 times a day


Employees who constantly switch between apps, 30 times or more, usually have an error rate of 28% higher than those who only use a few apps


The average person performs 134 copy and paste actions each day

The last point highlights that employees are often forced to switch between apps using the same data they used to complete a task, especially QA testers who have the same daily steps to check if everything works well. Taking this situation into account, extensions can help immensely and remove this unnecessary “copy-paste” from your quality assurance.

We interviewed some testers and checked all popular quality assurance forums to see which Chrome extension(s) for quality assurance testing they use to make their work more efficient and speed up test executions. Here we go.


We start our list with Capture – a solution that stands out as the unrivalled leader in bug tracking. Capture is the #1 solution for creating the most informative bug reports. It streamlines your bug-reporting process and enhances collaboration between testers and developers.
