Why browser extensions deserve a closer look in schools

Much of the software teachers and students use throughout the day runs in a browser, and browser extensions sit right in the middle of it. These small tools live inside Chrome, putting helpful features just a click away without requiring educators to switch between applications.

They're also remarkably easy to install. A teacher can add an extension in seconds, often without going through the district's usual technology approval process. That convenience is part of their appeal, but it also introduces challenges for school and district leaders responsible for keeping technology secure and manageable.

None of this makes browser extensions inherently unsafe. Many schools use them successfully every day. But they deserve the same thoughtful evaluation as any other technology that may interact with student or staff information.

Drawing on our own experience, here's what district leaders should know about evaluating browser extensions.

Extensions introduce another layer of oversight

When a district adopts a new software platform, there's typically a process for reviewing the vendor and its security practices, along with a plan for managing access.

Browser extensions work  differently. Chrome extensions are distributed through the Chrome Web Store, which manages how they're delivered and updated on users' devices. While vendors develop and submit updates, they have less direct control over when those updates reach users and may have limited visibility into where their extensions are installed.

For school districts, that can make it harder to maintain a complete picture of the technology being used across their schools, especially when extensions are installed outside established approval processes.

What to consider: How is the extension distributed and updated? What visibility does the vendor have into where it's installed?

Districts need visibility into what's installed

Many districts use Google Admin to manage extensions on school-issued Chromebooks, allowing IT teams to approve specific tools and control how they're deployed.

But not every device or browser environment is managed the same way. Where individual installations are permitted, teachers and students may add extensions outside the district's usual approval process. Depending on how devices and browsers are configured, those extensions may not appear in a central inventory or be covered by existing vendor agreements.

The result can be gaps in visibility, particularly when an extension is centrally managed on some devices but individually installed on others. Without a complete picture of what's installed, it's harder for district technology teams to maintain consistent oversight.

What to consider: Can your technology team identify where an extension is installed, manage access, and remove it when necessary?

Browser permissions deserve careful attention

One of the biggest advantages of browser extensions is that they can work directly within the websites educators already use. But depending on their permissions, they may also be able to read or modify information on those pages, including sensitive student or staff information.

Consider how many systems a teacher accesses throughout the day, from student information systems and gradebooks to learning management platforms and email. An extension with broad site permissions may have access to information across some or all of these environments.

That's why districts should understand what permissions an extension requests and whether they're necessary for its intended purpose. It's also important to consider how those permissions or the extension's functionality might change through future updates.

What to consider: What information can the extension access, and how will the district be informed if its permissions change?

Security requires ongoing maintenance

Approving an extension is only the beginning. Like any software, extensions need regular updates, security reviews, and a clear plan for long-term support.

An extension may continue to function even after a vendor has shifted its development resources elsewhere. And because extensions are often smaller components of a larger product, it's worth confirming that they're included in the same security and maintenance practices as the primary platform.

Districts should feel comfortable asking vendors how frequently extensions are updated, whether they're included in security assessments, and what happens if support is discontinued.

What to consider: Is the vendor committed to maintaining the extension to the same standard as its core product for as long as educators and students are using it?

Six questions to ask before approving a browser extension

Asking the right questions can help district technology teams evaluate extensions with greater confidence:

1. Who is responsible for the extension? Is it published by a trusted vendor and covered by the appropriate agreements and security reviews?
2. How will we manage it? Can the district centrally deploy, monitor, and remove it across managed devices?
3. What information can it access? What permissions does it require, and are they necessary for its intended purpose?
4. How is it maintained? Is it regularly updated and included in the vendor's security assessments?
5. What happens if it's discontinued? Will educators retain access to their saved work, and what functionality would they lose?
6. Is there another way to accomplish the same task? Does the vendor's primary platform already offer the functionality educators need?

These questions offer a practical starting point for making informed decisions about the technology districts bring into their classrooms.

Why we retired our Chrome extension

We've worked through these same questions ourselves.

Early in MagicSchool's journey, we introduced a Chrome extension to make it easier for teachers to access MagicSchool while working in other browser tabs. It was a practical way to bring AI-powered support into educators' everyday workflows.

Since then, MagicSchool has evolved. Our web platform is now home to capabilities like Raina, Studio Mode, District Knowledge, and student tools, supported by the privacy and safety protections we've continued to strengthen. As we've invested in the platform, our Chrome extension hasn't kept pace.

As part of our ongoing security review process, including work associated with our SOC 2 audit, we took a closer look at the different ways educators access MagicSchool. We encountered some of the same challenges outlined above, particularly limited visibility into individual installations and the ongoing maintenance required to bring the extension in line with the standards we've established for our core platform. We also had limited ability to communicate directly with users through the Chrome Web Store.

Ultimately, we decided our resources would be better focused on the platform where we can deliver the strongest experience for educators. The MagicSchool Chrome extension was retired on October 30, 2026.

Teachers who have used the extension will retain access to their MagicSchool accounts and saved work through the web app. Our Help Center article explains what to expect and how to continue using MagicSchool.

We know educators build routines around the tools they use, and retiring a feature is a decision we take seriously. It's also part of our responsibility to focus on experiences we can confidently support and continue improving.

Building a more thoughtful approach to classroom technology

Browser extensions will continue to play a role in schools, and districts can take practical steps to manage them responsibly. Maintaining a list of approved extensions, managing deployment centrally where possible, and periodically reviewing what's installed can help technology teams maintain oversight.

Districts should also expect transparency from their technology partners about how products work and how they'll be supported over time. At MagicSchool, we hold ourselves to those same expectations. Earning the trust of educators and district leaders means continually evaluating what we build and making thoughtful decisions about where we invest.
