What is a Browser Extension?
Extensions are applications that run inside the browser and provide additional functionality, integration with third party websites or services, and customized browsing experiences.
Are extensions fetched from the web every time the browser is loaded?
Extensions are downloaded by you browser upon install, and are subsequently run off of the local disk in order to speed up performance. However, if a new version of the extension is pushed online, it will be automatically downloaded in the background to any users who have the extension installed. Extensions may also make requests for remote content at any time, in order to interact with a web service or pull new content from the web.
