Features & Capabilities

Teams Phone Fix is a Chrome extension designed to fix Microsoft Teams phone call functionality issues by impersonating the Microsoft Edge browser's user agent. This helps overcome the "browser not supported" error encountered in Microsoft Teams, especially for Linux users or those using unsupported browsers.

The extension works silently in the background by modifying the user agent header, ensuring smooth phone call experience without manual interaction. It requires specific browser permissions for effective user agent rewriting and works best after reloading the Teams tab. Privacy is respected as it does not send data externally except to teams.microsoft.com. Users can customize the user agent within the extension settings. The source code is open and licensed under Mozilla Public License 2.0.

User Reviews

Teams Phone Fix is a Firefox add-on that successfully bypasses Microsoft Teams' restrictions on Firefox by faking the user agent, allowing users to join calls with video and sound on Windows, Mac, and Linux. It works well for 1-to-1 calls and partly for group calls. However, users face issues such as malfunctioning screen sharing, buggy chat interfaces, scrolling problems, and occasional connection failures. The add-on does not support launching the installed Teams app and sometimes requires restarting Firefox. Overall, it provides a useful workaround for Firefox users needing Teams access, with some functional limitations.

Pros

Effectively bypasses Microsoft Teams' intentional block on Firefox by faking the user agent, allowing users to join meetings without needing the official Teams app.
Enables working calls with video and sound on multiple platforms including Windows, Mac, and Linux (Ubuntu).
Works well for 1-to-1 calls and group calls to some extent, improving participation in Teams meetings through Firefox.
Quick to update and easy to use without complicated setup or tutorials.
Provides a solution for users who prefer Firefox over the Teams app or Chrome, avoiding installing additional software.

Cons

Screen sharing does not work with this add-on.
Group calls have limited functionality or issues; some users report inability to join group calls reliably.
Using the add-on can cause glitchy behavior in the Teams interface within Firefox, such as scrolling issues and buggy chat screens.
Does not open the installed Teams app if that is desired; limited to browser use only.
Some users experience connection errors like "Sorry, we couldn't connect you," requiring removal of the add-on to resolve.

Is Teams Phone Fix Safe?

Risk impact

Risk impact measures the level of extra permissions an extension has access to. A low risk impact extension cannot do much harms, whereas a high risk impact extension can do a lot of damage like stealing your password, bypassing your security settings, and accessing your personal data. High risk impact extensions are not necessarily malicious. However, if they do turn malicious, they can be very harmful.

Teams Phone Fix requires some sensitive permissions that could impact your browser and data security. Exercise caution before installing.

Risk likelihood

Risk likelihood measures the probability that a Firefox add-on may turn malicious. This is determined by the publisher and the Firefox add-on reputation on Firefox Add-ons Store, the amount of time the Firefox add-on has been around, and other signals about the Firefox add-on. Our algorithms are not perfect, and are subject to change as we discover new ways to detect malicious extensions. We recommend that you always exercise caution when installing a Firefox add-on.

Teams Phone Fix has earned a fairly good reputation and likely can be trusted.
