Fluco Toolbox: Extensity

Welcome to Fluco Toolbox, a series of posts that showcases potential edtech tools for the Fluvanna County classroom. Each post will discuss the tool, the type of problems it can help solve, and how it can be used in the classroom. If you’re a Fluvanna County staff member and want to learn more about using the tool in your own classroom, please schedule to see your ITRT and we will develop professional development based on your needs. If you’ve stumbled upon this post and you’re not part of the district, no worries! Feel free to use the information provided to jumpstart your own research.

Have you ever found your Chrome browser running slowly? Do you have a lot of extensions installed that you use often, and don’t want to uninstall any of them?

Today’s Fluco Toolbox tool is: Extensity

First, the basics:

Name: Extensity
URL: Chrome Web Store link
Cost: FREE
Problem this tool solves: Use this extension to turn extensions on and off at the click of a button and keep your Chrome browser running smoothly.

If you’re anything like me, you may have a lot of extensions installed on your Chrome browser. These extensions all have some purpose, but unfortunately, having too many extensions running at a time can slow down your browser. You may find that you have uninstalled all that you can, yet there are still so many extensions active. Extensity makes it easy to turn extensions on and off as needed without uninstalling them.

First, go to the Chrome web store link above and add the extension to the Chrome browser. Give any necessary permissions. The Extensity icon looks like a sideways yin-yang and is blue and white.

Whenever an extension needs to be disabled, simply click on the Extensity icon to see all active extensions. Click on the extension to turn it off. It will now appear to be grayed out. Click the extension again to turn it on.


Extensity also gives users the option to create Profiles. For example, if there are a set of extensions used only for work or shopping, then a profile can be created that allows certain extensions to be enabled/disabled when the profile is selected.

To create a profile, click on Extensity and then click the gear to access settings. Next, click the white “Profiles” button. Give the profile a name, such as “Work”. Click the + to add the profile. You’ll be asked to then select the extensions that should be enabled/disabled when using that profile. There are also options to select All or None. When finished, select “Save” and then “Close”. The next time you want to use a newly created profile, simply click on the Extensity icon and choose the preferred profile.


I often use Extensity when there are extensions I use from time to time, but not every day. I only activate them when I need to use them, and leave them off the rest of the time. This keeps my Chrome browser running smoothly, and can do the same for yours!
