Oh, forgot to mention for people like me who have to use another device for internet access or if you want a better way to figure out what the addons are you can go to the extensions website: https://extensions.blender.org/ once you click on the addon you want you click on Get addon. Under the drag and drop sections is a download link. For those who want to you can click and hold mouse button down and drag from the drag and drop section to blender and this will install the extension/addon. You can install the downloaded zip file by either dragging and dropping it in blender window or thru the addon section of preference just like you use to do.
