About Extension Manager / Backup

With this extension, you can toggle extensions on and off or remove them without opening the settings page. You can also save a list of currently installed extensions as a JSON file. By sharing this JSON file with friends or using it on another PC, you can instantly install the same set of extensions. It’s safe to use, as it won’t affect any extensions that are already installed.
