A wealth of Chrome extensions available for software testers make our lives easier. They add more functionality to the browser, helping get more work done in a short time. Extensions come in useful when you need to test web page UI or performance, make a screenshot to add to a bug report or clear a browser cache. Furthermore, they are lightweight and easily accessible.
So we decided to share a comprehensive list of Chrome extensions for software testers to make your life a little easier, too.
We’ve decided that the best way to start this list is by sharing what the QA Madness team uses the most frequently. Below, you’ll find some of their favorite tools.
VPN can be a big part of geolocation testing. In the sea of alternatives, it may be difficult to reach a consensus on functionality vs cost. Free VPNs can be limited in their usage, and paid services can be quite pricey or not meet your expectations.
Touch VPN is a great option that does not compromise quality. It is a free and unlimited service, with many advantages:
This extension is efficient for software testing particularly because it is operational in 90+ countries. Thus, you can quickly switch between GeoIPs during geolocation testing and finish this phase faster.
JavaScript is special in many ways. One of its situational vices, however, is its asynchronous nature. In other words, you are not able to delay a program’s execution for a desired amount of time.
JavaScript Pause/Resume extension allows you to create intervals while running the code to take care of other stuff. This plugin has only one function, yet it saves time by adding more time – a paradox really. Also, you are much more likely to avoid callback hell with this app.
Every user’s cache needs to be cleaned periodically to avoid issues such as delay, data corruption, and security endangerment. A regular cache-clearing procedure on Chrome takes 6 steps and involves a bit of scrolling and locating. To make this task simpler and quicker, Clear Cache extension implements the same function but with a single click.
For developers and QA engineers saving just a few moments can make a big difference. And when it comes to cache, refreshing it regularly is particularly important due to frequent updates and alterations of the projects they are working on. Clear Cache allows you to swiftly tidy up stored data by pressing the app’s icon after adding it to the browser. You can also enter the plugin’s settings and change the type of files to be removed as well as periods to be included during the ‘cleansing’ process.
GoFullPage is a very simple and intuitive tool for capturing a webpage fully with minimal effort. What makes this extension special is that it was created with fellow QA engineers in mind. As the creator stated, they have used many similar apps but were unable to capture a webpage in its entirety at once. Therefore, they decided to make an app that was capable of this.
After installing the extension, you just need to pin the plugin in your browser, turn it on, and relax for a few seconds while the extension does its job. You will notice the page being scrolled down without you moving the mouse, which is how GoFullPage operates to free you from performing any extra actions. After the screen is captured, you will be able to download it in a range of formats, such as PDF and PNG, and use the files as desired.
CSS Selector Helper is a great organizer. The main function is listing all CSS selectors in a smart window integrated into your dev tools. Thus, instead of straining your eyes over dozens of selectors, with the help of this app you can speedily skim through the presented catalog and work with needed options.
The grid with all CSS selectors presents element IDs and CSS classes with an established hierarchy – from ancestor elements to the selected variant. Among other features are:
Overall, it is a fairly simple and convenient addition to your testing toolkit.
Dimensions is a clear-cut plugin that helps precisely measure distances between elements. The way it works is very simple. Your cursor transforms into the center for horizontal and vertical rulers that are projected from the middle. The two perpendicular lines adjust automatically when detecting the elements on a webpage. As you move the mouse, the cross grid follows it, quickly locating visual components. In the same manner, a small box trails the cursor around, momentarily showing the space between parts of the design.
What is quite useful is the set of shortcuts the extension functions with. You can fully focus on the screen while using key combinations to perform desired actions.
This tool is very specific. Yet, it was able to find its niche and become quite popular for developers and QA engineers working with Magento.
Magento Form Filler was created with one specific function in mind, as is deductible from the name, – filling user information. The app uses default dummy data for user form, which can be saved and applied as needed. Further, you can add more users and adjust their info if desired.
Time is money, speed is key, thus, for agents involved with Magento, this extension is able to save those crucial minutes.
GTM is an incredibly useful tool not only for developers and QA engineers, but also marketers and web analysts. If you have never used Google Tag Manager before, it might not be the easiest app to grasp. However, spending a few moments on understanding the basics will save a lot of time in the long run.
This extension allows keeping all tags implemented on a webpage(s) under a single interface. You can create multiple GTM accounts and apply as many containers as needed for convenient navigation. Some of the main functions are:
GTM permits you to avoid editing the site code and use third-party tools with ease and no delays. Further, the plugin is achieving more popularity each day, and the developers regularly update it for better functionality.
This extension helps with monitoring Meta pixels present on a webpage. After completing the installation process, the plugin will work in the background, e.g. it will be highlighted upon detecting the presence of a Meta pixel. You can click on the tool’s icon and it will provide a list of all acting pixels and info on what they are tracking. Each pixel is provided with corresponding event info, e.g.:
In case a pixel is not functional, Pixel Helper will notify you that a Meta pixel is present but the conversion code was not loaded, i.e. this snippet of code does not function properly. It is a straightforward plugin that helps determine what works and what does not. Hence, you will know where to put your effort next.
Ghost Inspector extension is great for automating regression testing. It permits recording automated webpage tests and running them as many times as needed. This plugin converts real-world interactions into automated tests. To better explain how it functions, let us go over the process’s basics:
After, you will be presented with the list of all recorded actions, passed/failed clauses, as well as the actual video recording of the session and the final screenshot to make sure the outcome is identical to the successful option.
You can save and schedule such tests’ reruns as you please and set self-destruction date/time in case this is required. Further, you are able to adjust privacy settings to deny or allow access to your info for other users.
Tag Assistant is a high-level QA extension that helps verify that all implemented tags work correctly. You can enable it on a current site or let it check all open tabs in your browser. When turning the plugin on, you will be provided with a list of all active tags. Each of them is accompanied by color-coded icons that let you know their status. From here, you will be able to select any desired tag and view available details.
What is more, you can greatly benefit from the extension’s Record function. Here is how it works:
This plugin is great for effective management and support of all tags you want to implement on your page.
Dashlane removes the burden of trying to remember all login or payment data by safely storing that info for you. With this extension, you have your own digital safe where each password is memorized and protected.

After integrating the plugin into your developer tools, you will be able to view ARC Toolkit’s main panel. In this menu, a set of tests is displayed. These can be run simultaneously and individually. In case any defects are found, the app will notify you in its Elements panel.
More specifically, with ARC Toolkit you can:
Any changes made can be quickly retested and results viewed via a fresh report. This extension is a fast solution for tough problems.
Digital accessibility testing is crucial for the modern world, where we celebrate humanity and each individual. During this testing, Screen Reader extension for Chrome will help you evaluate how well a webpage is set up for people with particular conditions.
This plugin converts text into information that can be conveyed through synthetic speech. This is a great way of investigating code and alt tags for visuals in order to make sure the site is available for all.
This plugin lets you effortlessly modify color schemes on any website. Unlike other similar extensions that try to alter original shades, High Contrast uses filters to overlay them on top of the page and make it easier on the eyes. A few options are available:
Also, High Contrast presents you with the choice of using the app on all or selected platforms, thus the experience can be customized for each consumer.
While not directly related to testing, Grammarly is popular among QA resources. For QA experts, it can be a handy instrument for quick report/email composing, editing, and proofreading. It can be added to your Chrome browser as an extension, but also can be accessed via the app’s official site.
Grammarly has a very user-friendly UI and offers quite a few useful functions:
In case you need a fast and efficient re-read of any documentation, this app will help save time and demonstrate your attention to details.
QA Chrome extensions provide a bunch of new opportunities to software testers who are working on UI testing. Our favorite tools in this category are Page Ruler Redux, WhatFont, PerfectPixel, and Window Resizer.
This extension comes in handy when a software tester deals with element spacing, such as margins and paddings. Page Ruler Redux is a simple UI testing Chrome extension that measures object height, width, and padding on both sides by placing a pointer over an element and dragging it to draw a ruler in the desired direction.
There is one more great feature for QA engineers – an ability to test alternative web pages in case you want to replicate some other design on your page. Page Ruler Redux helps you find the defects that would be complicated to notice otherwise and deliver a pixel-perfect product.
When it comes to fixing issues with font size, color, and style, the QA Madness team recommends using this Chrome extension. It verifies the used font family and size for a particular section on a web page.
WhatFont enables you to quickly identify a particular text on a web page. It is faster than doing it without an extension (which is right-click > go to the elements > check the CSS > see the info). Instead, click on the WhatFont icon and hover the pointer over the word. The extension will instantly show you the font name with all the details (color, weight, etc.)
This tool allows comparing the original design with the actual design on the frontend. You can put a semi-transparent image overlay over the HTML for pixel perfection comparison. The list of the plugin’s features includes:
