Not really a computer program, but a list of all the best sites to visit that all spawn from a single folder in Firefox. It's opinionated, and one of the links is of course Hackernews, but also other sites like lobste.rs and old.reddit.com/r/programming etc Firefox lets you spawn a bunch of tabs and it saves me from having to manually click each link's URL. I use it very heavily. I am very thankful for the `Open all in tabs` feature.
