What is Manifest V3 (MV3)?

Manifest V3, or MV3, refers to a significant update to the WebExtensions API used to build browser extensions for Chrome, Firefox, and other Chromium-based browsers such as Edge and Opera.

What is the latest update to MV3?

As per the latest updates to MV3, the injection of remote code will no longer be allowed. This means any custom code that is configured for additional capabilities in Advanced Customization (AC) can't be previewed using Whatfix Studio's Preview mode.

How does the MV3 update impact you?

Whatfix will release its MV3-compliant Studio extension by May 15, 2024. After the upgrade to the MV3 extension, if your account relies on AC code for certain features, those specific capabilities can't be previewed using the Preview mode.
However, all other Whatfix content can be previewed as usual. There is no impact on the end-user experience, including features supported by AC code.

What is Whatfix's solution?

As the MV3 update will not enable you to preview AC code changes, Whatfix is actively developing self serve features that will provide you with out-of-the-box capabilities that do not require any code to be added in AC.
Some features, such as customizing fonts, setting Technical Preferences, and identifying User/Language have already been released as part of the Q1 R1 2024 release.

What is the timeline for the changes?

While Google is enforcing MV3 guidelines beginning June 2024, Whatfix plans to release its MV3-compliant Studio extension by May 15, 2024. Consequently, Whatfix will not be supporting Advanced Customization's (AC) Code Editor for new accounts created after May 15, 2024.

What action do you have to take as part of the MV3 update?

If you're using AC code to achieve certain out-of-the-box capabilities, shift to the available product features by May 15, 2024. Your Customer Success Manager (CSM) will be guiding you through the migration process.
If any of your use cases can't be migrated by May 15, 2024, you can use Whatfix's Developer extension to preview any AC code changes.

How can I get more information on the MV3 update?
