There are literally thousands upon thousands of extensions.
There’s another rub: You can install so many extensions that you can bring the browser to a creaking halt under the weight of the system resources that the extensions themselves consume. So, I set myself a challenge – a shortlist of the seven best Chrome extensions. Extensions that are really useful, well-supported, and do a good job.
Here’s the list I came up with – all these extensions are free and work on Windows, Mac, and Linux. 

Speedtest by Ookla | Test upload and download speeds

You may be familiar with the webpage for Ookla’s internet speed test, and now you can add a Chrome extension for faster and easier testing. The extension adds a button to your Chrome toolbar for one-click ping, upload, and download speed testing. You can also test to see how fast individual sites load, which is a great tool for web developers wanting to test new layouts or page elements.

Alternatively, just click on the FoxClocks icon next to your address bar for quick access to your clocks, without leaving the current web page. As an added bonus, FoxClocks deals with daylight saving time so you don’t have to! Note the warning that Google has about doing this: Warning: Google Chrome cannot prevent extensions from recording your browsing history. To disable this extension in incognito mode, unselect this option.

Bitly is a Chrome extension that is perfect for social media marketing and content creators. It creates custom, shortened links for websites, YouTube channels, and even Instagram posts, saving on character limits so you can write better calls to action to drive engagement and traffic. It’s also great for anyone who wants to share links in messenger apps without having to copy and paste a wall of text.

Momentum | Personalize your new tabs

Momentum may not exactly boost your productivity like other extensions on this list, but it turns boring, blank new tabs into personalized motivational slides. Each new tab will show a motivational quote and inspirational photo along with any to-do lists and website shortcuts you have. You can also set up friendly reminders to help you answer emails and attend meetings or get at-a-glance weather updates.

Deadname Remover | Ease into social transitioning

This extension is designed for anyone who is going through a social transition and wants to try out a new name. The plugin automatically replaces your old name with your new one in emails, web pages, and browser-based programs so you can test out a name without too much commitment. A word of warning though: If you aren’t ready to let other people know you’re trying out a new name or socially transitioning, this extension will let others see your new name in email chains and certain browser-based programs like Roll20.
