The Firefox 136.0 update finally adds my favorite feature from other browsers

Have you given a vertical tab layout a try before? If you haven't, it's a new take on the traditional tab formats that browsers use. Instead of them stretching horizontally across the top of your browser, vertical tabs put them in a sidebar. It's a little weird at first, but it has a few benefits over horizontal tabs: you can see the names of each website without them getting squished together, and you can scroll through them like you would any other list.
