Google’s Manifest Version 3 (MV3) Change #
All Chrome-based browsers are affected by changing the extension standard called Manifest Version 2 (MV2) to one called Manifest Version 3 (MV3). Those changes are major architectural changes that Google (creator of Chrome Browser) says will improve performance and security.
GAT Labs has been preparing for these changes for the last 2 years. This change is mandatory and will affect nearly all extensions deeply integrated with Chrome including Shield.
Please migrate before the 1st of July 2024 to ensure your domain will be up-to-date with Chrome updates.
Start the migration #
To start the migration navigate to GAT Shield > Manifest V3 Migraition (1)
An explanation window will be displayed by clicking on the red Start migration (2) button.
This will incite the migration in the backend. An email will be sent as confirmation.
A new window will be displayed, with follow-up steps that need to be taken.
The required steps will be shown in the Shield UI and these how-to instructions.

The steps will be explained below.
