I love this extension! There are a lot of quick dials, but many are not open source, and collect user data. I Love that it saves your links in bookmarks, rather than a cloud service, letting you choose to use Firefox sync or back them up to a file. Much better for user privacy. There are plenty of customization options, like choosing your own icons instead of screenshots. It's also very lightweight, so there's no delay before it loads every time you open a tab like there is with some similar extensions. An easy 5 stars!
