Overview
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.
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.
To preview such changes, Whatfix has introduced a Preview extension. This extension enables you to test any AC code used to achieve certain out-of-the-box capabilities. For more information, see Use Preview extension to test Whatfix content.
Whatfix enables you to use Whatfix Studio to install the Preview extension. This needs to be done only once, after which the Preview extension is updated automatically. For more information, see FAQs about Preview Extension.
Prerequisites
Before you migrate to the Preview Extension, here are some things you need to keep in mind.
What is Advanced Customization (AC) code?
Whatfix enables you to perform most tasks using the Whatfix user interface. For tasks that are not as frequently used, you can use certain snippets of Advanced customization (AC) code to perform specific capabilities using Whatfix. To verify if your account contains any AC code, see [Access Code Editor](/studio/docs/access-code-editor){target=`_blank`}.
Do I need the Preview extension even if I use a development environment?
You need to use the Preview extension only if you use Whatfix Studio to test any AC code in your account. If you have configured a development environment using JS Embed for testing, you don't need the Preview extension.
Are end users impacted by the Preview extension?
No, end users are not impacted by the Preview extension, as the AC code will be bundled within the Whatfix production extension or JS embed.
Can I use Google Chrome Store to install the Preview extension?
Whatfix Preview extension is best installed from the Whatfix Store. Whatfix store provides faster auto-updates, a better performance, and an overall streamlined deployment process.
