Chrome Extensions vs Add-ons

Recently, we announced that we are limiting staff to approved Extensions (we have been limiting students to approved extensions for quite a while). Staff can request additional extensions. This may be a good time to explain the difference between an Extension and an Add-on. (As a bonus, Web Apps will also be discussed).


Extensions allow you to customize the browser experience. Extensions can add functionality, tailor browser behavior to individual preferences, or integrate another application into the browsing experience. Extensions can be found in the browser just after the Omnibox (URL box). You can also find the extensions that you’ve installed by clicking on the triple buttons | More tools… | Extensions link.

Extension Examples:

Here are just a few popular examples:

  • One Tab – Condense all your open windows to one web page.
  • – Annotate and Bookmark web pages. You can join or create Groups as well.
  • Monosnap – Take screenshots, record video, add arrows, boxes and more. Great for creating visual directions.


Add-ons are extra tools that extend the use of Docs, Sheets, Forms, and Slides. These “add on” functionality to those programs. Add-ons are installed within each application. You would visit the Add ons Menu.

Add-on Examples:

  • AutoCrat – Mail merge for Docs.
  • Grackle Docs – Make your Docs ADA compliant. (This is an exciting new feature that the district is rolling out to all users – look for more information soon).
  • QR Code generator – makes QR codes.

All users should be careful with Add-ons. Generally, you are granting these add-ons the ability to see and manipulate your data. Although we are not limiting Add-ons at this time, we are monitoring the landscape for these as well.

Web Apps

Web Apps are a third category of applications that use a browser. These are applications that run within a browser. These are “stand-alone” applications that will run within their own tab.

Final Thoughts

The world is definitely changing. Many things that we do are getting easier and easier. To quote the wonderful “Hamilton” broadway play, “how lucky we are to be alive right now”.  With all the great features and powerful opportunities, we need to change and adapt to the new landscape. Unfortunately, those with bad intent are changing as well. Thus, we have to constantly monitor our safety and security.

It can be challenging to understand the differences among an Extension, Add-on, and Web App. The important part is to understand what permissions you are giving. It is really important that you understand the end effect of these applications.

Upcoming Google Changes

The web is an ever-changing landscape. Here are some upcoming changes in Google Applications:

Calendar Event Creators

You will soon be able to tell who booked a room on the Room Resource. In Find a Time, simply hover over the event and you will see who Created (thus booked the room) the event. This can be extremely useful when you need to see if someone can “swap” a room with you.

Available: Now

Priority page in Drive

You can access the Priority page from the left-hand navigation panel in Drive. Some features you’ll see on the Priority page include:

  • Priority:
    • Here you’ll see the documents we think are most relevant to you right now. These machine-learning-powered suggestions are based on various signals from your activity. On each suggested document, you can also take actions in line, without navigating to the doc in question, like replying to a comment or reviewing recent edits.
  • Workspaces:
    • In Workspaces, you’ll be able to see intelligent suggestions of related content to group together for easier access— like multiple files related to the same project.
    • You can also create your own personalized Workspaces collecting any files you have access to, including content stored in your My Drive and various Team Drives.
      • Right-click on any file and select Add to Workspace to dynamically group files as you work.

Availability: Rolling out throughout April

Tasks – Start Times, Repeating Tasks & Import Reminders

Google is adding three highly-requested features to Tasks. You can now:

  • Set a date and time for your tasks and receive notifications
  • Create repeating tasks
  • Import reminders into Tasks

Availability: Now

Images in Google Sheets

Google has made it simpler to add images inside of cells in Google Sheets.

On Desktop:

  • Via the menu bar at the top of a Sheet: Insert > Image > Image in cell

On Mobile:

  • Tap once on a cell to select
  • Tap again to bring up menu: Insert > Tap the “+” at the top of the screen > Image > Image in cell 
You can have multiple cells containing an image in a Sheet, but note that only one image per cell is possible at the moment.
Images inside cells will be associated with a row and move along with the data—so, if you move rows, filter or sort them, the images will move with the content in the row, unlike previously when images would sit on top of the grid.
Using the formatting and alignment tools, you can pin the image to a specific corner of the cell or set the alignment how you’d like. By default, images will align to the bottom left corner of the cell.

Availability: Rolling by April 15th

Chrome Extensions

Chrome extensions can be wonderful. These can add great functionality to the Chrome browser. Unfortunately, Chrome extensions can also be used by those with ill intent. Recently, we have seen a rash of employees having trouble with their browsers due to installing a Chrome extension. Many of these users didn’t even realize that they installed the extensions. For instance, I received this email just the other day:


When I posted my blog today, three advertisement links popped up😱
The teacher who sent this had installed several extensions that “helpfully” added advertisements. (This was not helpful at all.)
I also received this one:
For some reason my browser has been acting up and will not let me go to google images.  Can I please get this fixed?  It says “web page blocked” when I try to open a new tab in chrome.
This employee had installed several extensions as well. One of those extensions redirected his searches to a site that purely provides advertisements.
Currently, we don’t restrict employees from the extensions that they can add. Students are restricted. Extensions must be approved by the district before a student can install an extension.

Installed extensions (Ads)

Here is a list of some extensions that employees have installed:

  • Ad Offers by GameDaddio
  • Ad Offers by GamesChill
  • Ad Offers by MapsScout
  • Advertising by Entrality
  • Advertising Offers by PlayZiz
  • ArcadeFiesta Advertising
  • ArcadeFrontier Ads
  • ArcadeStar Advertising
  • Ball Pin Pal Ad
  • Battle Terrain Advertising
  • BoredPlay Advertising
  • BrainyZanyGames ads

You can see a general trend here (and we didn’t even make it out of the B’s).

Why is this a problem?

Ad sites frequently send the user to a different place. As you can see from the emails above, this can lead to frustration. This is also a potential security risk. As the bad actors get more sophisticated, the potential for harm increases.

Approved Extensions – Students

Currently, extensions must be approved prior to students installing them. We publish a list of the approved extensions for students on the Technology Blog.

Checking for Extensions:

You can easily check to see which extensions you have installed.

  • Click on the three buttons in the top right-hand corner of the Chrome browser (to the right of your picture/avatar)
  • Select “More tools…”
  • Select “Extensions” from the pop out

Click pattern to open extensions

This will open a new page. This page will list all of the extensions that you have installed. The page of extensions will also allow you to remove any extensions that you don’t want (unless the extension is District installed).  The example below is an example of 1Password as an extension (note the “Remove” button).

1Password extension

*1Password is a “paid for” extension that I purchased. 

District Installed Extensions

The District can “force” install extensions. The only one that we are currently installing is Clever.

District Approved Extensions

In addition to the Student Approved Extensions, we are currently comfortable with the following:

  • Google Cast for Education – allows teachers to have students screen share to a projector (via desktop)
  • WAVE – review ADA compliance of a website
  • – annotation for the web

We will be reviewing Extensions over the next few months.

Apps vs Extensions

Just to confuse things more, individuals can also install Chrome Apps. Although these will appear similar, extensions enhance the Chrome browser. Apps run within the browser. For your purposes, you can consider them the same.

Changes this Summer

Starting this summer, all extensions will need to be whitelisted in order to be installed. This will include staff as well as students. Starting this summer, any Chrome extension (or App) not approved will be removed. Currently, we are reviewing the extensions and Apps installed by all users.

Action for YOU to Take

  • Review the extensions that you have installed.
  • Remove extensions that you don’t need or want.
