I like that it is very fast to load, easy access to other features (like user accounts), good customer support - quick replies with answers or links when needed! It's not much of an issue for me at this point but sometimes takes quite some time before pages will be loaded without jumping back-and forth between different tabs in my browser window.
Good software overall. Very useful tool especially if you use social media sites such as Facebook/Twitter etc., where data can get "lost" easily over
