An update on Chrome Extensions

On July 10, Chrome for Developers published a blog post detailing all the upcoming changes for Chrome Extensions. Some bits of information worth highlighting are:

Manifest V2 phase out

The phase out for Manifest V2-based extensions has officially started. Back on June 3rd, users started receiving warnings for extensions that were still running on MV2. The next phase of this process is automatically disabling extensions running on MV2, however users can re-enable the extensions manually.

New action.openPopup API

Starting in version 127 of Chrome, the action.openPopup API will be available. This change aims to make Chrome more consistent with Firefox and Safari browsers.

Side Panel UI update

An update was made that added a pin icon to easily re-open side panels linked to extension's action icon and removed the previous global side panel icon.

Upcoming features

There are a number of upcoming features such as supporting multiple user script worlds in extensions, as well as the ability to provide a set of icons for dark mode specifically.
